In mathematical optimization and computer science, heuristic (from Greek εὑρίσκω "I find, discover") is a technique designed for solving a problem more quickly when classic methods are too slow for finding an approximate solution, or when classic methods fail to find any exact solution. This is achieved by trading optimality, completeness, accuracy, or precision for speed. In a way, it can be considered a shortcut. seating chart wedding alphabeticalWebNov 24, 2024 · As heuristic you can select every function h for which: h is admissible: h (u) <= dist (u, t) (never overestimate) h is monotone: h (u) <= cost (u, v) + h (v) (triangle … pub theme
