Each of the OSL Quadratic Programming Solutions modules:

1. Oslqslv for solving QP problems using simplex methods,
2. Oslqbslv for solving QP problems using interior point methods,

has its own user's guide. The following comments apply to both programs.

Example 1

oslqslv "?" > qslv.opt

This puts the list of keywords options for the oslqslv program, with explanations of their meanings and default values, into the file named "qslv.opt."

Example 2

oslqbslv -dspace=500000 -imaxiterb=70 -input=test1.mps -output=test1.out

The oslqbslv program is started and instructed to take input data from the file named "test1.mps." Output will be directed to the file named "test1.out." The program workspace will be set to 500000 16 byte words, and the value of the integer control variable Imaxiterb will be set to 70, which will make oslqbslv switch to a simplex method after 70 interior point barrier iterations.

Example 3

oslqslv @option.fil

The oslqslv program is started, and instructed to take its options from the file named "option.fil."

An options file should contain program options, one per line, as they would be entered on-line without the preceding minus sign.
