Windward Technologies, Inc. Windward Technologies, Inc. (WTI) is a company dedicated to the development and marketing of advanced numerical and visualization software technologies. WTI has special programs designed to serve commercial software developers, corporate software developers, and end users. Optimization Products Optimization problems can be difficult and time consuming to solve and no single optimizer is best in all cases. This is why WTI offers a family of optimizers; each one designed to take advantage of specific problem characteristics. The special characteristics range from linearity of variables to sparsity of gradients. GRG2 Generalized Reduced Gradient method. Our best optimizer for small to medium-sized problems (up to 100 variables and 100 constraints) where there is no special characteristic to exploit. LSGRG Large scale generalized reduced gradient method. An excellent optimizer for large problems (more than 100 constraints, up to several thousand). LSGRG exploits sparsity of the gradient matrix and handles large sparse problems efficiently. SQP Sequential Quadratic Programming method. SQP may be preferred to GRG2 when function evaluations are expensive. An excellent optimizer when the problem is quadratic in most of its variables. SLP Sequential Linear Programming method. An excellent optimizer when the problem is linear in most of its variables. SLP exploits linearity in problem variables and sparsity of the gradient matrix to handle large sparse problems efficiently.
