# The programs in this directory are "student" versions that # restrict problem sizes (to 300 variables and 300 general # constraints) and are intended for noncommercial use. # For serious commercial use, you should (eventually) license # commercial versions, even if your applications never exceed # the limits of the student versions. For simplicity, these # are 32-bit Power PC binaries, which generally also run on # Intel Macs (albeit more slowly than native Intel binaries). # Should feedback suggest it warranted, Intel student binaries # could be made available. file README file ampl.gz for student ampl processor file cplex.tgz for gzipped tar file with student CPLEX 11.0.1 solver and LICENSE file gjh.gz for "solver" that computes the objective gradient (g), the constraint , Jacobian (J), and the Hessian of the Lagrangian (H) at the , current point (primal and dual variable values). The solver , message shows commands to read these as params and delete , the temporary file that conveys them. When multiple objectives , are present, the first is used unless the objectives have suffix , objweight ==> g is the gradient of the weighted sum of objectives. , Source = /netlib/ampl/solvers/examples/gjh.c. file gurobi.tgz for student GUROBI solver for LP/MIP problems file lpsolve.gz for LP/MIP solver based on lp_solve 4.0; see ampl/solvers/lpsolve/README file minos.gz for student MINOS solver file snopt.gz for student SNOPT solver
