[Help-glpk] GLPKConstants - legend

[JanaT]

Hello!

I´m trying to get along with GLPK and Java and have some problems understanding
how to use it.

Defining constraints the GLPKConstants are used. Is there somewhere a list to
explain them? Or is there a tutorial? Googling the question does´t help. The (2
or 3) examples I found do not explain my questions...

What means GLPKConstants.GLP_CV?
GLPK.glp_set_col_kind(lp, 1, GLPKConstants.GLP_CV);

What means GLPKConstants.GLP_DB?
GLPK.glp_set_row_bnds(lp, 1, GLPKConstants.GLP_DB, 0, 0.2);



Thank You,
Jana
