Which function will select the lowest expansion node at first for evaluation?a. Greedy best-first searchb. Depth-first searchc. Breadth-first searchd. Both A and B

You are developing a navigation system for a self-driving car. The system needs to find the shortest path from the car's current location to a specified destination on a map. The map is represented as a graph, where nodes represent intersections and edges represent roads connecting the intersections. Each road has a length associated with it. You decide to use the Best-First Search algorithm with a heuristic function that estimates the straight-line distance between two intersections.QuestionWhat would be the most appropriate criterion for selecting the next node to expand in the Best-First Search algorithm for the self-driving car navigation system?a)The depth of the nodeb)The straight-line distance to the destination from the nodec)The breadth of the noded)The cost associated with the node

"The search first begins from the root node and the first one of the child node's sub-tree is completely traversed. That is, first all the one-sided nodes are checked, and then the other sided nodes are checked."Which search algorithm is described in the above definition?1 pointThe Breadth First Search (BFS)The Depth First Search (DFS)The A* searchNone of the aboveOther:

Which search is complete and optimal when h(n) is consistent?ans.Best-first searchA* searchDepth-first searchBoth Best-first & Depth-first search Previous Marked for Review Next

Breadth-first search is not optimal when all step costs are equal, because it always expands the shallowest unexpanded node.ans.IrrelevantFalseTrueexpanded Previous Marked for Review Next
