Andrew, Would it be possible to have a simple example on this new dimacs like data format? I presumed that this new format only applies to GLPK, not on MathProg. An example will be easy to visualise the new data format, in my case. Noli On 1/7/10, Andrew Makhorin wrote: > Below here is a draft

[Help-glpk] lp/mip problem data in dimacs-like format

2010-01-07 Thread Andrew Makhorin
Below here is a draft description of dimacs-like format to represent lp/mip problem data. Text files in this format are human-readable and suitable for processing with text tools like sed, gawk, etc., so this format can be used in glpk as a basic low-level format. Any comments are appreciated. Tha
