Branch and Bound Combinatorial Optimization via Negative Cost Functions in Algorithms
Branch and Bound is a combinatorial optimization algorithm that improves upon general backtracking by utilizing admissible cost functions defined for partial states to prune the search tree. The core theoretical mechanism relies on the property that these extended cost functions are non-decreasing along any branch of the search space, allowing the algorithm to discard suboptimal subtrees when their lower bound exceeds the current best solution's objective value (minimum cost). This concept operates within discrete optimization theory, specifically bridging exact search methods by integrating bounding logic into depth-first exploration strategies.
