Webthe CSP can be solved in O(nd2) time as compared to general CSPs, where worst-case time is O(dn). For tree-structured CSPs you can choose an ordering such that every node’s parent precedes it in the ordering. Then you can greedily assign the nodes in order and will find a consistent assignment without backtracking. Web(d) Realizing this is a tree-structured CSP, we decide not to run backtracking search, and instead use the e -cient two-pass algorithm to solve tree-structured CSPs. We will run this two-pass algorithm after applying the unary constraints from part (a). Below is the linearized version of the tree-structured CSP graph for you to work with.

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 WebSolving CSPs–Backtracking Search • Bad news: 3SAT is a finite CSP and known to be NP-complete, so we cannot expect to do better in the worst case • Backtracking Search: …
