The Repair library provides two simple, fundamental features which are the basis for the development of repair algorithms and non-monotonic search methods in ECLiPSe:
This functionality allows the implementation of classical local search methods within a CLP environment (see Tutorial on Search Methods). However, the central aim of the Repair library is to provide a framework for the integration of repair-based search with the consistency techniques available in ECLiPSe, such as the domains and constraints of the FD library.
A more detailed description of the theory and methods that are the basis of the Repair library is available .
To use the repair library you need to load it using
Normally, you will also want to load one more of the ’fd’, ’ic’, ’fd_sets’ or ’conjunto’ solvers. This is because of the notion of tenability, i.e. whether a tentative value is in a domain is checked by communicating with a different solver that keeps that domain.
