Csp heuristics
WebNov 4, 2013 · CSP is a problem.. Backtracking is an algorithm that searches for a solution, basically, by trying every possibility, and backtracking as soon as it knows it is … WebOracles: the solution found to previous CSPs in the sequence are used as heuristics to guide the resolution of the current CSP from scratch. Local repair: each CSP is calculated starting from the partial solution of the previous one and repairing the inconsistent constraints with local search.
