An optimal deadlock resolution algorithm in multidatabase systems
In this paper, we propose a novel deadlock resolution algorithm. In the presence of global deadlocks in a multidatabase system, this algorithm always selects an optimal set of vic...

Real-Coded Adaptive Range Genetic Algorithm Applied to Transonic Wing Optimization
Real-coded Adaptive Range Genetic Algorithms (ARGAs) have been applied to a practical three-dimensional shape optimization for aerodynamic design of an aircraft wing. The real-code...

Convergence of Ant Colony Optimization on First-order Deceptive Systems
Deceptive problems have been considered difficult for ant colony optimization (ACO) and it was believed that ACO will fail to converge to global optima of deceptive problems. Thi...

Supporting Global Numerical Optimization of Rational Functions by Generic Symbolic Convexity Tests
Convexity is an important property in nonlinear optimization since it allows to apply efficient local methods for finding global solutions. We propose to apply symbolic methods t...

Optimal Rank Reduction for Linear Context-Free Rewriting Systems with Fan-Out Two
Linear Context-Free Rewriting Systems (LCFRSs) are a grammar formalism capable of modeling discontinuous phrases. Many parsing applications use LCFRSs where the fan-out (a measure...
