Complexity of a CHR Solver for Existentially Quantified Conjunctions of Equations over Trees for syntactic equality of rational trees that performs unification. We first prove its exponential complexity in time and space for non-flat equations and deduce from this proof a quadratic complexity for flat equations. We then present an extended CHR solver for solving existentially quantified co

Cost-Based Filtering for Stochastic Inventory Controlh a known non-stationary probability distribution. Under a widely-used control policy for this type of inventory system, the objective is to find the optimal number of replenishments, their timings and their respective order-up-to-levels that meet customer demands to a required service level. We ext

Solving First-Order Constraints in the Theory of the Evaluated Treesr formula . into an equivalent disjunction . of simple formulas in which the solutions of the free variables are expressed in a clear and explicit way. The correctness of our algorithm implies the completeness of a first-order theory built on the model of Prolog III.
