On the Use of Boolean Methods for the Computation of the Stability Number

نویسنده

  • Alain Hertz
چکیده

We study a transformation of pseudo-Boolean functions which, when applicable, amounts to constructing from a graph G = (V, E) a new graph G’ = (V’, E’) with the same stability number and such that 1 V’1 = 1 VI 1. This transformation provides a polynomial time algorithm for the computation of the stability number of graphs which contain neither an induced chordless cycle with four vertices, nor its complement. The transformation might also be useful for reducing the size of a claw-free graph while preserving its stability number.

A Fast and Self-Repairing Genetic Programming Designer for Logic Circuits

Usually, important parameters in the design and implementation of combinational logic circuits are the number of gates, transistors, and the levels used in the design of the circuit. In this regard, various evolutionary paradigms with different competency have recently been introduced. However, while being advantageous, evolutionary paradigms also have some limitations including: a) lack of con...

A New Method for Considering Distribution Systems in Voltage Stability Studies

In methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. Distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...
