Logistic Constraints on 3D Termite Construction
Abstract. The building behaviour of termites has previously been modelled mathematically in two dimensions. However, physical and logistic constraints were not taken into account i...

Testing Properties of Constraint-Graphs
We study a model of graph related formulae that we call the Constraint-Graph model. A constraintgraph is a labeled multi-graph (a graph where loops and parallel edges are allowed)...

Numeric State Variables in Constraint-Based Planning
We extend a planning algorithm to cover simple forms of arithmetics. The operator preconditions can refer to the values of numeric variables and the operator postconditions can mod...

Models and branch-and-cut algorithms for pickup and delivery problems with time windows
In the pickup and delivery problem with time windows (PDPTW), capacitated vehicles must be routed to satisfy a set of transportation requests between given origins and destination...
