the name of the .nl file to open
a structure which handles the pointer to the problem
the starting point
the lower boundaries
the upper boundaries
the dual starting variables
the lower boundaries of the constraintes
the upper boundaries of the constraintes
ampl_init reads a AMPL .nl file and initialize a structure which handles a pointer to the problem. It returns also some parameters related to the problem (like boundaries, etc.).
