Uncertainty in dynamic constraint satisfaction problems
"... Abstract. Many real life problems that can be modeled as Constraint Satisfaction Problems (CSPs) come from uncertain and dynamic environments, so the original solution found might become invalid after changes. Here, we study the problem of find-ing robust solutions for CSPs under the assumptions tha ..."

Nogood Recording for Static and Dynamic Constraint Satisfaction Problems
- International Journal of Artificial Intelligence Tools
, 1993
"... Many AI synthesis problems such as planning, scheduling or design may be encoded in a constraint satisfaction problem (CSP). A CSP is typically defined as the problem of finding any consistent labeling for a fixed set of variables satisfying all given constraints between these variables. However, fo ..."

that may be used for solving both static and dynamic CSPs. It offers an interesting compromise, polynomially bounded in space, between an ATMS-like approach and the usual static constraint satisfaction algorithms. 1 Introduction The constraint satisfaction problem (CSP) model is widely used to represent
Solution reuse in dynamic constraint satisfaction problems
- In Proceedings of the 12th National Conference on Artificial Intelligence
, 1994
"... Many AI problems can be modeled as constraint satisfaction problems (CSP), but many of them are actually dynamic: the set of constraints to consider evolves because of the environment, the user or other agents in the framework of a distributed system. In this context, computing a new solution from s ..."

Arc consistency in dynamic constraint satisfaction problems
- In Proceedings AAAI'91
, 1991
"... Constraint satisfaction problems (CSPs) provide a model often used in Artificial Intelligence. Since the problem of the existence of a solution in a CSP is an NP-complete task, many filtering techniques have been developed for CSPs. The most used filtering techniques are those achieving arc-consiste ..."

"... . An important extension of constraint technology involves problems that undergo changes that may invalidate the current solution. Previous work on dynamic problems sought methods for efficiently finding new solutions. We take a more proactive approach, exploring methods for finding solutions mo ..."

Grid Workflow Recovery as Dynamic Constraint Satisfaction Problem
"... Abstract—With service level agreements (SLAs) the Grid broker guarantees to finish the Grid jobs by a given deadline. There are a number of approaches, to plan reservations to fulfil these deadline requirements and to handle currently running jobs in the case of a resource failure. However, there is ..."

An Improved Algorithm for Maintaining Arc Consistency in Dynamic Constraint Satisfaction Problems

Solving Dynamic Constraint Satisfaction Problems by Identifying Stable Features

"... This paper presents a new analysis of dynamic constraint satisfaction problems (DCSPs) with finite domans and a new approach to solving them. We first show that even very small changes in a CSP, in the form of addition of constraints or changes in constraint relations, can have profound effects on s ..."
