The orienteering problem (OP) and prize‐collecting traveling salesman problem (PCTSP) are two typical TSPs with profits, in which each vertex has a profit and the goal is to visit several vertices to optimize the collected profit and travel costs. The OP aims to collect the maximum profit without exceeding the given travel cost. The PCTSP seeks to minimize the travel costs while ensuring a minimum...
In recent years, drinking water pollution happens from time to time, severely endangering social stability and residents’ life. By placing sensors in urban water supply pipes to monitor water quality in real time, the negative impacts of pollution accidents can be reduced to a great degree. However, how to localize pollution source in real time according to the detection information from water quality...
Genetic algorithm has made lots of achievements in the aspect of solving constrained optimization problems, but engineering design problem is one of typical optimization problems for complicated constraint condition and correlative variable parameters. The results optimized by classical mathematical optimization method are often poor. In this paper, one hybrid search strategy was designed aiming to...
