[Help-glpk] interpretation of 'glp_print_sol' and 'glp_print_ranges'

[Robbie Morrison]

Hello Andrew

I am currently trying to decode the output from
'glp_print_sol' (also glpsol --output).  It looks
like a subset of the output from
''glp_print_ranges' (also glpsol --ranges).  Just
the second call is documented in detail, though.

It seems that the 'glp_print_sol' prints status
"B " and 'glp_print_ranges' prints status "BS" for
an inactive constraint or basic variable.

The ranges call is also described here:

  
http://en.wikibooks.org/wiki/GLPK/Solution_information#Sensitivity_analysis_report

I looked at 'glpapi11.c' but could not see a
compelling reason from these abbreviations not
being both "BS".  Is there a semantic difference?

If there is a difference, I will make a note on
the GLPK wikibook.  If not, should they not both
print "BS".

with best wishes, Robbie
