LNCS 3709 - LP as a Global Search Heuristic Across Different Constrainedness Regions Author: Lucian Leahu and Carla Gomes Subject: Websearch methods were provided by abstract models of backtrack search that show that, under certain conditions, such procedures provably exhibit heavy-tailed behavior [6, 13, 33, 34]. Main Results So far, evidence for heavy-tailed behavior of randomized backtrack search procedures on concrete instance models has been largely em-pirical.
