Glpk implements only the subset described in the document "GLPK:
Modeling Language GNU MathProg" (it is included in the distribution in
pdf format). AMPL provides much more modeling features, for example,
ordered sets, features to describe network models in terms of nodes and
arcs, features to describe non-linear models, etc.
