This paper describes an Evolutionary Algorithm that ree pairs to solve Constraint Satisfaction Problems. Knowledge about propp erties of the constraints network can permit to deene a tness function which is used to improve the stochastic search. A selection mechanism which exploits this tness function has been deened. The algorithm has been tested by running experiments on randomly generated 3-...

Downlo roRNAs (miRNA), a class of natural RNA-interfering agents, have recently been identified as attractive s for therapeutic intervention. The rationale for developing miRNA therapeutics is based on the premise berrantly expressed miRNAs play key roles in the development of human disease, and that correcting miRNA deficiencies by either antagonizing or restoring miRNA function may provide a ...

For motion planning it is important to have an accu rate dynamic system model and in many cases friction is an important component of the model It is known however that when Coulomb friction is added to the rigid body dynamic equations the forward dynamic solution may not exist and if it exists it is not necessarily unique In this paper we study the existence and uniqueness prop erties of the f...

A major challenge still facing the designers and implementors of database programming languages (DBPLs) is that of query optimisation. We investigate algebraic query optimisation techniques for DBPLs in the context of a purely declarative functional language that supports sets as first-class objects. Since the language is computationally complete issues such as non-termination of expressions an...

Some new regularities found in the pseudoscalar meson octet are reported. They invite to reconsider models where elementary fermions and composite QCD open strings can be grouped in common supermultiplets.
