Several variants of backtracking exist. Backmarking improves the efficiency of checking consistency. Backjumping allows saving part of the search by backtracking "more than one variable" in some cases.

WebCSP – Goal Decomposed into Constraints Backtracking Search: a DFS that • chooses … WebNotice that our backtracking search already works with normal CSPs; you should simply define factors that output real numbers. For CSP construction, you can refer to the CSP examples we have provided in util.py for guidance (create_map_coloring_csp() and create_weighted_csp()). You can try these examples out by running: python run_p1.py
