The Ant Lion Optimizer (ALO) mimics the hunting mechanism of antlions in nature. Five main steps of hunting prey such as the random walk of ants, building traps, entrapment of ants in traps, catching preys, and re-building traps are implemented.

Multi-objective version of ALO is called Multi-Objecive Ant Lion Optimizer (MOALO).
