Tabu

Tabu, in data analysis and optimization, is a technique used to find better solutions in complex problems by keeping track of recent moves or solutions to avoid repeating them. It helps prevent getting stuck in local optima—suboptimal solutions that appear best within a limited area—by temporarily forbidding certain choices. This "memory" guides the search toward unexplored options, increasing the chances of discovering a more optimal overall solution. Think of it as a strategic way to remember and avoid revisiting past mistakes, encouraging a broader and more effective search for the best outcome.
