Many optimization methods are available at the present time. The software that implements a particular method may not be available to all users or the software may require a compiler not readily available to all users. The software may require extensive modifications before it can run on a...

Fair and Jaffeen[Fair and Jaffee1972] considered the econometrics of models of markets which were not in equilibrium. The estimation of disequilibrium models has proved difficult. Because of this the model was chosen to be a member of a test suite of optimization problems by Dorsey and...

Interval arithmetic and computational (automatic) differentiation are powerful methods for use in optimization. Interval arithmetic operates on interval values rather than points and can be used to examine large areas of a space, often eliminating portions shown not to contain the global...
