- A.
Pronalazenje puta najvece tezine
- B.
Pronalazenje puta najmanje duzine
- C.
Pronalazenje puta najmanje tezine
- D.
Pronalazenje puta najvece duzine
Correct Answer
C. Pronalazenje puta najmanje tezineExplanation
The correct answer is "Pronalazenje puta najmanje tezine" which translates to "Finding the path with the least weight." In the context of searching strategies in graphs, this means finding the path between two nodes that has the lowest total weight or cost. This is often done using algorithms such as Dijkstra's algorithm or the Bellman-Ford algorithm, which calculate the shortest path based on the weights assigned to the edges of the graph.Rate this question:

- C.
Procena cene putanje do cilja pod uslovom da prolazi kroz cvor n
Correct Answer
C. Procena cene putanje do cilja pod uslovom da prolazi kroz cvor nExplanation
In the A* search algorithm, the function "f(n) = g(n) + h(n)" represents the estimated cost of the path from the start node to the goal node, passing through node n. The function takes into account two factors: g(n) represents the accumulated cost of the partial path from the start node to node n, while h(n) represents the heuristic estimate of the remaining cost from node n to the goal node. By summing these two values, the algorithm can prioritize nodes that have a lower estimated cost, leading to more efficient search and finding the optimal path.Rate this question:

In the A* search algorithm, the function "f(n) = g(n) + h(n)" is used to estimate the cost of a path. In this context, "h(n)" refers to the heuristic estimation of the remaining cost of the path from node "n" to the goal node. This heuristic estimation helps guide the algorithm towards the goal by considering the potential cost of the remaining path. It is a crucial component in determining the priority of nodes to be explored and ultimately finding the optimal path in the search process.Rate this question:

- C.
Najvecu dozvoljenu dubinu pri otvaranju cvorova pretrage
Correct Answer
A. Redosled otvaranja cvorova pretrageExplanation
Strategije pretrage definisu redosled otvaranja cvorova pretrage. To znači da strategije pretrage određuju u kojem redosledu će se otvarati cvorovi tokom pretrage, što može imati značajan uticaj na efikasnost pretrage. Na primer, strategija pretrage u širinu će otvarati sve cvorove na jednom nivou pre nego što pređe na sledeći nivo, dok će strategija pretrage u dubinu otvarati cvorove sve do najveće dozvoljene dubine pre nego što se vrati na prethodni cvor. Dakle, redosled otvaranja cvorova pretrage je ono što strategije pretrage definišu.Rate this question:

- D.
Ukupnog broja generisanih (otvorenih) cvorova
Correct Answer
B. Ukupnog broja memorisanih cvorovaExplanation
The correct answer is "Ukupnog broja memorisanih cvorova" because the spatial complexity of a problem can be measured by the total number of nodes stored in memory during the execution of an algorithm. This includes both the nodes in the OPEN list (nodes that have been generated but not yet expanded) and the nodes in the CLOSED list (nodes that have been expanded and their successors have been generated). The total number of generated nodes may be larger than the number of nodes stored in memory at any given time, as some nodes may have been expanded and removed from memory.Rate this question:

- A.
Da
- B.
Ne
- C.
Nije bitno
Correct Answer
A. DaExplanation
In A* algorithm, h(n) represents the heuristic function which estimates the cost from the current node to the goal node. The algorithm combines the actual cost from the start node to the current node (g(n)) and the heuristic cost from the current node to the goal node (h(n)) to make decisions on which path to explore. Therefore, it is possible for the estimate h(n) to be 6 if the heuristic function overestimates the actual cost.Rate this question:

- A.
Pretrage u sirinu
- B.
Usmerene pretrage
- C.
Nije bitno
- D.
Pretrage u dubinu
Correct Answer
A. Pretrage u sirinuExplanation
The given heuristic function h(n) = C * (1/d(n)) in the A* algorithm is inversely proportional to the depth of the nodes in the search graph. This means that nodes with smaller depths will have larger heuristic values, while nodes with larger depths will have smaller heuristic values. In the beginning of the algorithm, when all nodes are at the same depth, the heuristic values will be equal for all nodes. This property aligns with the breadth-first search strategy, where nodes at the same depth are explored before moving to nodes at deeper depths. Therefore, the algorithm will exhibit the property of breadth-first search in the beginning.Rate this question:

Ako u A* algoritmu h(n) zadovoljava uslov monotonosti, da li se može desiti promena ukazatelja u toku izvršenja programa GRAPHSEARCH:
- A.
Da
- B.
Ne
- C.
Nije bitno
Correct Answer
B. NeExplanation
In the A* algorithm, the heuristic function h(n) represents the estimated cost from node n to the goal node. If h(n) satisfies the condition of monotonicity, it means that the estimated cost from any node n to the goal node is always less than or equal to the actual cost from n to the goal node. Therefore, there is no need to change the pointer during the execution of the GRAPHSEARCH program as the estimated cost will always be consistent and reliable.Rate this question:

Cvor u grafu moze istovremeno biti i roditelj i dete:
- A.
Tacno
- B.
Netacno
Correct Answer
A. TacnoExplanation
In a graph, a node can be both a parent and a child at the same time. This is possible in cases where there is a cycle in the graph, meaning that there is a path that starts and ends at the same node. In such cases, the node will have an incoming edge as a child and an outgoing edge as a parent, making it both a parent and a child simultaneously. Therefore, the statement "A node in a graph can be both a parent and a child at the same time" is true.Rate this question:

Usmerene pretrage
- B.
Pretrage u sirinu
- C.

Correct Answer
A. Usmerene pretrageExplanation
If h(n) satisfies the condition of monotonicity in the A* algorithm, it means that the estimated cost from the current node to the goal node is always less than or equal to the estimated cost from the current node to any successor node plus the estimated cost from that successor node to the goal node. This property ensures that the A* algorithm will always find the optimal solution. Therefore, in the GRAPHSEARCH program, which includes directed searches and breadth-first searches, the change of pointers during execution will not affect the correctness of the algorithm as long as h(n) remains monotonic.Rate this question:

In the given scenario, the search is performed iteratively with increasing depth limits. This approach is commonly known as iterative deepening depth-first search (IDDFS). In IDDFS, the search starts with a depth limit of 1 and gradually increases the limit by 1 in each iteration. This strategy allows the search to explore the tree in a depth-first manner while still guaranteeing completeness. Therefore, the given scenario can be equated to a breadth-first search, as it explores the tree level by level, similar to how breadth-first search operates.Rate this question:

The correct answer is "Selekcija, krosover, mutacija". This is because genetic algorithms typically involve three main operators: selection, crossover, and mutation. Selection involves choosing individuals from a population based on their fitness for reproduction. Crossover involves combining genetic material from two parents to create offspring. Mutation involves introducing random changes in the genetic material to promote diversity and exploration of the search space. The given answer includes all three of these operators, making it the correct choice.Rate this question:

Ako se temperatura u SA algoritmu suvise sporo menja:
- A.
Konvergencija je brza
- B.
Konvergencija je spora
- C.
Ne utice na konvergenciju
Correct Answer
B. Konvergencija je sporaExplanation
If the temperature in the SA algorithm changes too slowly, it means that the algorithm takes a longer time to converge. This is because the SA algorithm uses temperature as a parameter to control the acceptance of worse solutions in order to explore the search space effectively. If the temperature changes slowly, it implies that the algorithm is not exploring the search space efficiently and is stuck in local optima. Therefore, the convergence of the algorithm is slow.Rate this question:

Proceduralna znanja su:
- A.
Znanja koja nastaju kao posledica primene procedura VI
- B.
Znanja koja proisticu iz stohastickih procedura VI
- C.
Neodvojiva od procedure koje ih koriste
Correct Answer
C. Neodvojiva od procedure koje ih koristeExplanation
Proceduralna znanja su neodvojiva od procedure koje ih koriste. This means that procedural knowledge cannot be separated from the procedure that utilizes it. In other words, procedural knowledge is closely tied to the specific process or procedure in which it is applied. It is a type of knowledge that is acquired through the experience of carrying out a particular procedure and is intimately connected to the steps and actions involved in that procedure.Rate this question:

Ako se temperatura u SA algoritmu suvise brzo smanjuje:
- A.
Nije od vaznosti za rad algoritma
- B.
Algoritam moze da promasi globalni ekstrem
- C.
Algoritam ce poceti da osciluje
Correct Answer
B. Algoritam moze da promasi globalni ekstremExplanation
If the temperature in the SA algorithm decreases too quickly, it means that the algorithm is cooling down rapidly. This can lead to the algorithm skipping over the global extreme point, which is the optimal solution. The algorithm needs a slower decrease in temperature to explore the search space effectively and converge towards the global extreme.Rate this question:

Jedna strategija je kompletna ako:
- A.
Uvek nalazi resenje, ako postoji
- B.
Da li ce naci resenje, zavisi od problema do problema
- C.
Ponekad i nadje resenje
- D.
Uvek nalazi resenje
Correct Answer
A. Uvek nalazi resenje, ako postojiExplanation
The correct answer is "Uvek nalazi resenje, ako postoji." This means that a strategy is considered complete if it always finds a solution, provided that a solution exists. This implies that the strategy is able to solve any problem that has a solution.Rate this question:

HC algoritam - Uspon sa slucajnim ponovnim kretanjem:
- A.
Nema direktnu vezu sa svojstvom kompletnosti
- B.
Tezi kompletnoj pretrazi sa verovatnocom 1
- C.
Tezi kompletnoj pretrazi sa verovatnocom 0.5
Correct Answer
B. Tezi kompletnoj pretrazi sa verovatnocom 1Explanation
The given answer states that the HC algorithm with random restarts tends to complete the search with a probability of 1. This means that, in most cases, the algorithm will find the optimal solution or a very good solution. The use of random restarts allows the algorithm to escape local optima and continue searching for better solutions. Therefore, the HC algorithm with random restarts is likely to provide a complete search with a high probability of finding the optimal solution.Rate this question:

Neka se SA (algoritam simuliranog kaljenja) primenjuje za minimizaciju kriterijumske funkcije. Tada se korak u kome se kriterijumska funkcija povecava:
- A.
Nijedno od ponudjenih odgovora
- B.
Ne prihvata
- C.
Prihvata sa nekom verovatnocom
- D.
Prihvata bezuslovno
Correct Answer
C. Prihvata sa nekom verovatnocomExplanation
In the simulated annealing algorithm, the step in which the objective function increases is accepted with some probability. This means that there is a chance that the algorithm will accept a worse solution in order to explore the search space and avoid getting stuck in local optima. Therefore, the correct answer is "Prihvata sa nekom verovatnocom" which translates to "Accepts with some probability".Rate this question:

Ako je heuristička funkcija u A* algoritmu oblika h(n)=C * (1/d(n)), gde je C konstanta, a d(n) dubina čvorova u grafu pretrage, pri kraju rada će algoritam imati svojstvo: ***
- A.
Pretrage u dubinu
- B.
Pretrage u sirinu
- C.
Nije bitno
- D.
Usmerene pretrage
Correct Answer
A. Pretrage u dubinuExplanation
The given heuristic function h(n) = C * (1/d(n)), where C is a constant and d(n) is the depth of the nodes in the search graph, implies that the A* algorithm will have the property of "Pretrage u dubinu" (depth-first search) at the end of its execution. This is because the heuristic function favors nodes with smaller depths, causing the algorithm to prioritize exploring deeper paths before considering shallower ones.Rate this question:

Correct Answer
C. Poseban oblik eksplicitnog znanja, koja se mogu interpretirati kao iskazi o necemuExplanation
Deklarativna znanja su poseban oblik eksplicitnog znanja, koja se mogu interpretirati kao iskazi o nečemu. To znači da su to znanja koja se izražavaju u obliku tvrdnji ili izjava, a mogu se jasno interpretirati kao informacije o određenim činjenicama, konceptima ili idejama. Ova vrsta znanja se može izraziti u pisanom ili usmenom obliku i često se koristi u akademskom i stručnom kontekstu.Rate this question:
