Within the customer–subcontractor negotiation process, the first problem of the subcontractor is to provide the customer with a reliable order lead-time although his workload is partially uncertain. Actually, a part of the subcontractor workload is composed of orders under negotiation which can be either confirmed or cancelled. Fuzzy logic and possibility theory have widely been used in schedul...

We analyze how fast we can solve general systems of multivariate equations of various low degrees over F2; this constitutes a generic attack on a hard problem both important in itself and often arising as part of algebraic cryptanalysis. We do not propose new generic techniques, but instead we revisit the standard exhaustive-search approach. We show that it can be made more efficient both asymp...

MOTIVATION Approximate tandem repeats (ATR) occur frequently in the genomes of organisms, and are a source of polymorphisms observed in individuals, and thus are of interest to those studying genetic disorders. Though extensive work has been done in order to identify ATRs, there are inherent limitations with the current approaches in terms of the number of pattern sizes that can be searched or ...

Binary sequences with low autocorrelations are important in communication engineering and in statistical mechanics as groundstates of the Bernasconimodel. Computer searches are the main tool to construct such sequences. Due to the exponential size O(2 ) of the configuration space, exhaustive searches are limited to short sequences. We discuss an exhaustive search algorithm with run time charact...

The efficiency of the cross-rotation function step of molecular replacement (MR) is intrinsically limited as it uses only a fraction of the Patterson vectors. Along with general techniques extending the boundaries of the method, there are approaches that utilize specific features of a given structure. In special cases, where the directions of noncrystallographic symmetry axes can be unambiguous...
