Hi,

I want to use JAMS solver to use emp for getting KKT of a linear model.

I have read the EMP manual but I did not understand how to interpret the MCP from result. Is there any special file which those equation is created?

I used the example of EMP manual as follow:

variables f,z; positive variables x,y;

equations g, h, defobj;

g… x + y =l= 1;

h… x + y - z =e= 2;

defobj… f =e= -3*x + y;

model comp / defobj, g, h /;

file info / ‘%emp.info%’ /;

putclose info / ‘modeltype mcp’;

solve comp using emp minimizing f;

— The solution report and solvar are as follow:

S O L V E S U M M A R Y

MODEL comp OBJECTIVE f

TYPE EMP DIRECTION MINIMIZE
