    Multirobot search for a stationary object placed in a known environment with a combination of GRASP and VND

  • Original language description

    The paper addresses the problem of multi-robot search for a stationary object in a priori known environment. Two variants of the problem are studied given the working environment represented by a graph. The first one is an extension of the Traveling Deliveryman Problem for multiple vehicles, while the second one is a generalization of the Graph Search Problem. A novel algorithm is presented to solve both these problems, which is based on a combination of Greedy Randomized Adaptive Search Procedure with Variable Neighborhood Descent. A set of experimental evaluations was conducted over the benchmark instances derived from the TSPLIB library. The results obtained show that the proposed approach outperforms state of the art approaches in quality of results for both problems. Moreover, computational times for problems with the size of few hundreds of vertices allow using the approach for on-line decision making in search and rescue scenarios.
