Currently, the robot is playing an increasingly significant role in managing a warehouse. This paper proposes an optimal method to help a warehouse robot make task decisions, which aims at minimizing the whole cost of completing multiple tasks. Firstly, Abstract Transition System (ATS) is used to model the warehouse environment, and Linear Temporal Logic (LTL) formula is used to formulate the tasks...
To solve the problem of searching speed of the shortest path in the electronic guide system, the binary heap of A* algorithm which combines binary heap with A* algorithm is proposed in this paper. The method stores the extended node position in the A* algorithm by binary heap, avoids traversal searching storage space, optimizes data structure of storage array, and reduces the algorithm searching time...
Vehicle routing problem with time windows (VRPTW) is a well-known NP-hard combinatorial optimization problem that is crucial for transportation and logistics systems. Even though the particle swarm optimization (PSO) algorithm is originally designed to solve continuous optimization problems, in this paper, we propose a set-based PSO to solve the discrete combinatorial optimization problem VRPTW (S-PSO-VRPTW)...
Test suite reduction is to find a subset of the test suite containing a minimal number of test cases that can satisfy all test requirements. Test suite reduction techniques attempt to remove redundant test cases. Existed minimal set selection methods cannot guarantee the optimality of representative sets obtained. This paper adapts the Quine-McCluskey algorithm to find the minimal representative set...
