Tabulation is a core technique in dynamic programming that enhances computational efficiency by storing intermediate results. It's used to solve complex problems by building up solutions from simpler sub-problems, as seen in calculating the Fibonacci sequence. This method reduces redundant calculations, optimizes time complexity, and is crucial in handling large datasets in fields like AI and machine learning.
