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.

Optimal rectangle packing: an absolute placement approach

TL;DR: These algorithms represent the current state-of-the-art for this problem, outperforming other algorithms by orders of magnitude, depending on the benchmark, and introduce three new benchmarks, avoiding properties that make a benchmark easy, such as rectangles with shared dimensions.

Temporal similarity measures for querying clinical workflows

TL;DR: This work describes a possible approach to the conceptual modeling of a clinical process, by using a temporally extended workflow model, and defines how a workflow case can be represented as a set of activities, and shows how to express them through temporal constraint networks.
