Real-life dynamic problems may lead to inconsistent constraints systems for which a solution must be found even if constraints have to be relaxed. In this paper, we propose a best-first search to handle such problems. Classical backtracking search algorithms are extended in two ways: identification of good backtrack points as in Intelligent Backtracking techniques and maximum use of independant work (that would have been discarded with a mere backtrack). We first describe an operational… CONTINUE READING
