Bottom-Left Fill

Constructive placement heuristic that drops each piece to the lowest-leftmost feasible position.

Also called: Bottom-Left Fill · BLF · 바텀-레프트

Last verified: 2026-05-27

A constructive placement rule: each piece is positioned as low as possible, then as far left as possible, without overlap; the "fill" variant also reuses gaps left by earlier placements. Often used as the inner placement step inside a metaheuristic search. Traces to Jakobs (1996).
