A Novel Self-Adaptive Trust Region Algorithm for Unconstrained Optimization
A new self-adaptive rule of trust region radius is introduced, which is given by a piecewise function on the ratio between the actual and predicted reductions of the objective function.

Necessary and sufficient condition on global optimality without convexity and second order differentiability [PDF]
The main goal of this paper is to give a necessary and sufficient condition of global optimality for unconstrained optimization problems, when the objective function is not necessarily convex. We use Gâteaux differentiability of the objective function

An Improved Chicken Swarm Optimization Algorithm and its Application in Robot Path Planning
Chicken swarm optimization (CSO) algorithm is one of very effective intelligence optimization algorithms, which has good performance in solving global optimization problems (GOPs). However, the CSO algorithm performs relatively poorly in complex GOPs for

Testing Unconstrained Optimization Software [PDF]
Much of the testing of optimization software is inadequate because the number of test functmns is small or the starting points are close to the solution. In addition, there has been too much emphasm on measurmg the efficmncy of the software and not enough on testing reliability and robustness.

Parameter Estimation of Electromechanical Oscillation Based on a Constrained EKF with C&I-PSO
By combining together the extended Kalman filter with a newly developed C&I particle swarm optimization algorithm (C&I-PSO), a novel estimation method is proposed for parameter estimation of electromechanical oscillation, in which critical ...
