Binary paint shop problem
WebSep 16, 2024 · We present a generalization of the binary paint shop problem (BPSP) to tackle an automotive industry application, the multi-car paint shop (MCPS) problem. The objective of the optimization is to minimize the number of color switches between cars in a paint shop queue during manufacturing, a known NP-hard problem. We distinguish … WebIt is well-known that there are instances of the binary paint shop problem for which the recursive greedy heuristic is better than the greedy heuristic. In this note, we give an example of a family of instances where the greedy heuristic is better than the recursive greedy heuristic, thus showing that these heuristics are uncorrelated.
