Hyper-heuristic

Hyper-heuristics represent a high-level methodology designed to choose, combine, generate, or adapt a range of simpler heuristics to solve complex computational search and optimization problems across various domains. Unlike traditional heuristics, which are problem-specific, hyper-heuristics operate on a higher level of abstraction, focusing on the heuristic selection process itself rather than on direct problem-solving.

This approach enables the development of more versatile and adaptive problem-solving systems. By incorporating machine learning techniques, hyper-heuristics learn from past experiences to improve their strategy over time, selecting the most appropriate heuristic or combination of heuristics based on the characteristics of the problem at hand.

One practical application of hyper-heuristics is in scheduling and timetabling problems, where there are numerous constraints and variables to consider, making it impractical to design a single heuristic that performs well across all instances. A hyper-heuristic system can dynamically select and adapt heuristics based on the specific requirements and constraints of each scheduling problem, such as allocating time slots for university lectures or scheduling staff shifts in a hospital.

Another example is in vehicle routing, where hyper-heuristics can efficiently manage the selection of heuristics for determining optimal routes under varying conditions, such as traffic, delivery windows, and vehicle capacity, significantly improving logistics and delivery systems' efficiency and reliability.
