Abstract. We give logarithmic approximation algorithms for the nonmetric uncapacitated multicommodity and multilevel facility location problems. The former algorithms are optimal u...
Abstract We show that if one can find the optimal value of an integer programming problem min{cx : Ax ≥ b, x ∈ Zn +} in polynomial time, then one can find an optimal solution...

This paper describes a number of general design problems with adventure-like computer games for young children in order to demonstrate the need for specific design guidelines for t...
: The generalized problem of placing n queens on an n-by-n board provides an "embarrassingly parallel" problem for parallel solution. This paper expands on the discussion...
Many combinatorial problems can be modelled as Constraint Satisfaction Problems (CSPs). Solving a general CSP is known to be NP-complete, so closure and heuristic search are usual...
