In this example we show how to use the OSInstance API to generate an OSiL problem instance.

The objective of this example is to illustrate how to build a problem instance using the OSIntance class API. In particular we illustrate a number of the set() methods in the OSInstance class. As written, we need the LINDO nonlinear solver.

Model: A nonlinear model with multiple local minimizers. Adapted from the Samples directory of the LINDO API

      maximize  abs( x0 + 1) + .4 * x1;  <br />
      s.t.      x0           + x1            <= 4; <br />
                x1 * x2      + ln(x2)        <= 6; <br />
                x0 * x1                      <= 0; <br />
                max(x1 + 1, x0)              >= 0; <br />
                if(x1, 1, x1)                <= 0; <br />
                (x1 * 2 * x1  -  x1) * x0    <= 0; <br />
                -100  <=  x0  <=  100              <br />
                x1 is binary                       <br />
                5 <= x2 <= 10; x2 is integer       <br />
