1). The domain barrier is a filter which prevents any problem specific information to be passed to the hyper-heuristic level (Burke et al., 2013), thus it LY2109761 allows the reusability of the selection hyper-heuristic components. Although the selection and the move acceptance methods are general and reusable, Bilgin et al. (2007) stated that using different combinations of the two methods yields to a different performance.
There is a large number of studies on heuristic selection and move acceptance methods used within selection hyper-heuristics (Burke et al., 2013).
