Abstract. This paper presents a class of NK landscapes with nearest-neighbor interactions and tunable overlap. The considered class of NK landscapes is solvable in polynomial time using dynamic programming; this allows us to generate a large number of random problem instances with known optima. Several variants of standard genetic algorithms and estimation of distribution algorithms are then applied to the generated problem instances. The results are analyzed and related to scalability theory for selectorecombinative genetic algorithms and estimation of distribution algorithms.
