Temporal constraint networks

TLDR
It is shown that the STP, which subsumes the major part of Vilain and Kautz's point algebra, can be solved in polynomial time and the applicability of path consistency algorithms as preprocessing of temporal problems is studied, to demonstrate their termination and bound their complexities.

Chance-constrained scheduling via conflict-directed risk allocation

TL;DR: Through a set of simulated car-sharing scenarios, it is empirically shown that conflict-directed risk allocation computes solutions nearly an order of magnitude faster than prior art does, which considers all constraints in a single lump-sum optimization.

The Twofold Integration of CBR in Decision Support Systems

TL;DR: This short paper presents the experience in facing different levels of integration of CBR techniques with other system components and techniques inside decision support systems for controlling environmental emergencies.

An Incremental and Non-binary CSP Solver: The Hyperpolyhedron Search Algorithm

TL;DR: This work proposes an algorithm called “Hyperpolyhedron Search Algorithm (HSA)” that solves non- binary constraint satisfaction problems in a natural way as an incremental and non-binary CSP solver.

Simple temporal problems in route scheduling for the dial---a---ride problem with transfers

TL;DR: This paper addresses a variant of the DARP where requests can change of vehicle during their trip, and proposes necessary and sufficient conditions to fasten the detection of unfeasible or feasible routes.

Probabilistic Temporal Networks.

TL;DR: A new model is defined, the Probabilistic Temporal Network, for representing temporal and atemporal information while fully embracing probabilistic semantics, which allows representation of time constrained causality, of when and if events occur, and of the periodic and recurrent nature of processes.

Maintaining knowledge about temporal intervals

James F. Allen
- 01 Mar 1991 - 
TL;DR: An interval-based temporal logic is introduced, together with a computationally effective reasoning algorithm based on constraint propagation, which is notable in offering a delicate balance between space and time.

Combinatorial optimization: algorithms and complexity

TL;DR: This clearly written, mathematically rigorous text includes a novel algorithmic exposition of the simplex method and also discusses the Soviet ellipsoid algorithm for linear programming; efficient algorithms for network flow, matching, spanning trees, and matroids; the theory of NP-complete problems; approximation algorithms, local search heuristics for NPcomplete problems, more.

Consistency in Networks of Relations

TL;DR: The primary aim is to provide an accessible, unified framework, within which to present the algorithms including a new path consistency algorithm, to discuss their relationships and the may applications, both realized and potential of network consistency algorithms.
