local search

Local search is a Problem-solving technique used in optimization that explores solutions nearby a current best option to find improvements. Starting from an initial solution, it examines neighboring solutions—those that are similar but slightly different—and moves to a better one if found. This process continues iteratively, aiming to find a better overall solution without evaluating every possibility. It’s like adjusting a design step-by-step to improve it, focusing on improvements close at hand rather than searching the entire solution space. Local search is efficient for complex problems where exhaustive searches are impractical.
