Solve this BIP model using LINGO software.

Now to formulate a BIP model, 1 if route j is chosen 0 otherwise Let x, be the jth element of the route matrix. For i=A, ,land j=l, the cost of route j. Now the objective function to minimize is, ,10. Let c' denote 10 With subject to, l0 yy, 2 -l 10 j-l y, e binary Now to formulate a BIP model, 1 if route j is chosen 0 otherwise Let x, be the jth element of the route matrix.
