摘要: The two-dimensional bin packing problem (2BP) consists in a set of rectangular items into rectangular, equally-sized bins. is NP-hard and has multitude real world applications. We consider the case where are oriented guillotine cutting free. In this paper we first present review well-know heuristics for 2BP then propose new ILP model problem. Moreover, develop multi-start algorithm based on probabilistic version LGFi heuristic from literature. Results compared to other well-known heuristics, using data sets provided obtained experimental results show that proposed returns excellent solutions. With an average percentage deviation 1.8% best know lower bounds it outperformes algorithms by 1.1%−5.7%. Also 3 500 instances tested upper bound was found.
