Dear Mr. Andrew, I need some help in writing MILP problems in GNU MathProg can you please help me with this. The problem is the following:
min p #39; d
s.t. c #39;? ? S
A? ? (? + d) ? 0,
A? + (? + d) ? 0,
?1 = 0,
?n = 1;
?i ? {0, 1} for i = 1, 2, . . . , n,
di ? {0, 1} for i = 1, 2, . . . ,m,
?i ? [0, 1] for i = 1, 2, . . . ,m.
where p is array with m elements, d is array with m elements (binary), A is mxn
matrix, c is array with m elements, w is binary array with m elements,
? is binary array with n elements.
Could you please help me with this, I really need this for my research.
THanks in advance.
Kind regards,
Igor Mishkovski
