For MILP problems (at least one integer variable), go to Using CPLEX: MIP.

Solves a Linear Programming (LP) problem given as a '.csv' file, using CPLEX (from a Fortran 90 calling program). The file: can be in "American" or "European" style. It must contain: in the 1.st row, the objective function coefficients; in the following rows, the constraints (see the base example).

#Suggested problems: juice, lp_juice.lp (z* = 403.125); diet, lp_diet.lp (z* = 14.856); HPW prb_19, lp_hpw19.lp (z* = 198.5); diet, lp_SAS_diet.lp (z* = 12.081)
