ly improves the solution with the help of limiting and controlling possible relocation regimes by a fix-and-optimize strategy, i.e. a small subset of “free” binary relocation variables. The majority of remaining binary variables are tentatively fixed to zero leading to a fast solvable truncated MIP

Rosemary Stewart from the literature. All implemented algorithms are evaluated using previously existing benchmark instances and by using a set of new very large-scale real-world instances. The results show that our approach yields good quality solutions within relatively short time.

The evolution is operated by a memetic mechanism and the offsprings must satisfy a distance test before entering the population. Information about better customer assignmen

r this concept is the same as that described in the context of hybrid algorithms based on instance reduction in Chapter 3: Even though it might be unfeasible to apply a MIP solver to the original problem instance, the solver might be particularly effective in solving the reduced ILP model in which a

Fifteen Young Leaders questions about their views on, and approach to, leadership. The fifteen were found by asking a variety of people for suggestions of young leaders in different kinds of job. ‘Young’ was set at under 35 for all except medical UGMs and the DGM who were considered young if they were under 40.
