This paper presents a multi-objective algorithm based on tissue P system (MO TPS for short) for solving the tri-objective vehicles routing problem with time windows (VRPTW). Unlike most of the work where just the accuracy or extensibility of the solution is the core, the proposed algorithm focuses on searching the boundaries of solution sets and ensuring the solutions have better extensibility and uniformly distributed. In MO TPS, the cells of the tissue P system are divided into two groups. The first group, consisting of only one cell, aims at...
