A Symmetry-Breaking Node Equivalence for Pruning the Search Space in Backtracking Algorithms
We introduce a new equivalence on graphs, defined by its symmetry-breaking capability. We first present a framework for various backtracking search algorithms, in which the equivalence is used to prune the search tree. Subsequently, we define the equivalence and an optimization problem with the goal...
