we have developed connect four implementation based on these ideas that runs on standard hardware without any special multiprocessing our version beats all commercially available apps and applications presently available when playing against them your challengeshould you care to take it onis to build better one front-end for this game is available in sect or on the text' website so you can build your own connect four game summary this covered heuristics and how they play part in problems when the search space grows too large for an exhaustive search many problems that would otherwise be unsolvable are solvable when heuristics are applied howeverthe nature of heuristic is that sometimes they work well and other times they may not if heuristic worked every timeit would be called technique and not heuristic we must think carefully about whether heuristic search is really required or not when solving problems choosing the right problem representationdata structureor algorithm is much more important than brute force approach and applying heuristic it may be that problem that seems too big to solve can be reduced to something that can be solved by the right algorithm when there is no such reduction possibleheuristic search may be the answer the search algorithms hill climbingbest firstand aare best remembered by comparing their algorithms to depth first search and breadth first search hill climbing is like depth first search except that heuristic is applied to order the newly added nodes to the stack best first is like breadth first search except that all the nodes on the queue are ordered according to the heuristic it is often implemented with priority queue the aalgorithm is like best first except that the queue is ordered by the sum of the heuristically estimated distance to the goal plus the distance travelled so far the minimax algorithm too uses heuristic when the search space is too large an effective game engine will always search as deep as possiblebut when the search must be cut offa good heuristic will help in estimating the worth of move in the game review questions answer these short answermultiple choiceand true/false questions to test your mastery of the which is fasterdepth first search or breadth first search which searchdepth first or breadth firstmay not complete in some situationswhen could that happen when hill climbingwhat could prevent the algorithm from finding goal nodethis copy belongs to 'acha
