MOST Question regarding Quadratic Gen Costs

[Stephen Suffian]

Hello all,

I have been able to succesfully run MOST for several days, but I recently
came across a problem when attempting to load cost data into mpc.gencost. I
My original gencost was below:

mpc.gencost = [
    2    0    0    2    200    0;
    2    0    0    2    300    0;
    2    0    0    2    500    0;
    2    0    0    2    1000    0;
];

When I changed it to quadratic, it works as long as the first term is 0.

mpc.gencost = [
    2    0    0    3   0    200    0;
    2    0    0    3   0    300    0;
    2    0    0    3   0    500    0;
    2    0    0    3   0    1000    0;
];

However, when I change the first term to a non-zero value:

mpc.gencost = [
    2    0    0    3   0.004    200    0;
    2    0    0    3   0    300    0;
    2    0    0    3   0    500    0;
    2    0    0    3   0    1000    0;
];

I get the following error.

error: mpopt2qpopt: Sorry, no solver available for MIQP models
error: called from
    mpopt2qpopt at line 92 column 13
    most at line 2065 column 14
    test at line 41 column 5

I am using the glpk solver. Does anyone know if this is a solver issue, a
human error (on my part) issue, or otherwise?

Thanks!
