Each of the OSL Linear Programming Solutions modules:

1. Oslsslv for solving LP problems using simplex methods,
2. Oslbslv for solving LP problems using interior point methods, and
3. Oslnslv for solving pure Network problems using special network simplex method,

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

Example 1

oslsslv "?" > sslv.opt

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

Example 2

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

The oslbslv 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 oslbslv switch to a simplex method after 70 interior point barrier iterations.

Example 3

oslnslv @option.fil

The oslnslv 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.
