Modelling exceptionally hard constraint satisfaction problems

BM Smith, SA Grant - Principles and Practice of Constraint Programming …, 1997 - Springer
Randomly-generated binary constraint satisfaction problems go through a phase transition
as the constraint tightness varies. Loose constraints give an 'easy-soluble'region, where …

CSPLib: a benchmark library for constraints

IP Gent, T Walsh - Principles and Practice of Constraint Programming–CP' …, 1999 - Springer
Constraint satisfaction algorithms are often benchmarked on hard, random problems. There
are, however, many reasons for wanting a larger class of problems in our benchmark suites …

[图书][B] Algorithms and heuristics for constraint satisfaction problems

problems, as well as an extensive and systematic empirical evaluation of these new …

In search of exceptionally difficult constraint satisfaction problems

BM Smith - International Workshop on Constraint Processing, 1993 - Springer
It has been observed by several authors that for many NP problems, a sharp peak in the
median cost to find a solution can be seen as an order parameter is varied; the peak occurs …

An algebraic approach to multi-sorted constraints

AA Bulatov, P Jeavons - … and Practice of Constraint Programming–CP …, 2003 - Springer
Most previous theoretical study of the complexity of the constraint satisfaction problem has
considered a simplified version of the problem in which all variables have the same domain …

Tractability by approximating constraint languages

MJ Green, DA Cohen - Principles and Practice of Constraint Programming …, 2003 - Springer
A constraint satisfaction problem instance consists of a collection of variables that need to
have values assigned to them. The assignments are limited by constraints that force the …

Constructing an asymptotic phase transition in random binary constraint satisfaction problems

BM Smith - Theoretical Computer Science, 2001 - Elsevier
The standard models used to generate random binary constraint satisfaction problems are
described. At the problem sizes studied experimentally, a phase transition is seen as the …
