We introduce BubbleSearch, a general approach for extending priority-based greedy heuristics. Following the frame cently developed by Borodin et al., we consider priority algorithms, which sequentially assign values to elements in some fixe adaptively determined order. BubbleSearch extends priority algorithms by selectively considering additional orders near good ordering. While many notions of nearness are possible, we explore algorithms based on the Kendall-tau distance (a as the BubbleSort… CONTINUE READING
