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.
