Rule reduction for efficient inferencing in similarity based reasoning
The two most important models of inferencing in approximate reasoning with fuzzy sets are Zadeh's Compositional Rule of Inference (CRI) and Similarity Based Reasoning (SBR). ...

On the job rotation problem
The job rotation problem (JRP) is the following: Given an n × n matrix A over R ∪ {−∞} and k ≤ n, find a k × k principal submatrix of A whose optimal assignment problem...

A New Approach to Exact Crossing Minimization
The crossing number problem is to find the smallest number of edge crossings necessary when drawing a graph into the plane. Eventhough the problem is NP-hard, we are interested in ...

Faster algorithms for computing Hong's bound on absolute positiveness
We show how to compute Hong’s bound for the absolute positiveness of a polynomial in d variables with maximum degree δ in O(n logd n) time, where n is the number of non-zero co...
