Metaheuristics are advanced problem solving algorithms that attempt to find the best solution to complicated combinatorial problems such as vehicle routing, airline scheduling, and inventory control. This research developed a framework such that metaheuristics can be expressed as subsets of “modules” from a common library, with a common structure. The standardized modules and structure allow these algorithms to modify themselves during their execution, by varying parameters and modules. This ability introduces the potential for semi-intelligent algorithms that are capable of learning. Novel metaheuristic concepts were developed and tested on the Arc Subset Routing Problem, a new problem which involves scheduling a vehicle to service a subset of roads in a network, such that benefit is maximised subject to a distance constraint. Several new methods for creating test problems and modelling results were also introduced. The findings suggest promising outcomes for these new metaheuristics concepts.
