Abstract
In this paper we introduce a framework built on top of the Knowledge Base System , which allows local search heuristics to be synthesized from their formal descriptions. It is introduced as a new inference to solve optimization problems in . To model a local search heuristic, users need to specify its components, among which neighbourhood moves are the most important. Two types of neighbourhood moves, namely standard moves and Large Neighbourhood Search moves, are supported. A set of built-in local search heuristics are provided, allowing users to combine neighbourhoods in different ways. We demonstrate how the new local search inference can be used to complement the existing solving mechanisms for logic programming.
