An Improved Version of the Out-of-kilter Method and a Comparative Study of Computer Codes

The primary objectives of the paper are fourfold: To present an improved formulation of the out-of-kilter algorithm; To give the results of an extensive computational comparison of a code based on this formulation with three widely-used out-of-kilter production codes; To study the possible sensitivity of these programs to the type of problem being solved; To investigate the effect of advance dual start procedures on overall solution time.
