This book is concerned with theory, algorithms and software for solving nonconvex mixed integer nonlinear programs. It consists of two parts. The first part describes basic optimization tools, such as block-separable reformulations, convex and Lagrangian relaxations, decomposition methods and global optimality criteria. The second part is devoted to algorithms. Starting with a short overview on...

results the results showed that compared to the control group, relaxation (23.2) and positive self-talk (21.25) treatment methods alone can reduce pms (p < 0.001). on the other hand, a combined (relaxation + positive self-talk) treatment method (13.75) was more effective in reducing pms compared to relaxation or positive self-talk alone. conclusions it seems that psychological therapy based on ...
