Abstract. We answer a question asked by Hajdu and Tengely: The only arithmetic progression in coprime integers of the form (a2 , b2 , c2 , d5 ) is (1, 1, 1, 1). For the proof, we ļ...
This work shows a modular architecture based on FPGA's to solve the eigenvalue problem according to the Jacobi method. This method is able to solve the eigenvalues and eigenv...
Many systems that learn from examples express the learned concept as a disjunction. Those disjuncts that cover only a few examples are referred to as small disjuncts. The problem ...
Due to its important practical applications, temporal planning is of great research interest in artiļ¬cial intelligence. Yet most of the work in this area so far is limited in at...
Freuder in (1991) deļ¬ned interchangeability for classical Constraint Satisfaction Problems (CSPs). Recently (2002), we extended the deļ¬nition of interchangeability to Soft CSP...
