11 Mar 2010 Binary Serach of rows of M-by-N Matrix Binary Search that is based on sum of column values of rows of input M-by-N Matrix Author: Dr. Murtaza Khan

This does not work well when there are many rows with the same column sum. I have a matrix of size ~45000 x 350 where the rows can have a sum of 1, 2 or 3; in this case the supplied function used about 100 times as long as the built-in matlab function. Also, if the same data is transposed the function does not work at all.

Other than that it seems to work very well for uniformly distributed data.

Works nicely with ILOG CPLEX 11 at least

23 Sep 2011 Linear Mixed Integer Program Solver Solve linear mixed integer problems with a branch and bound method. Author: Thomas Trötscher Y., BIG

I like to use this file for the folowing mathematical model but I have never used Matlab before. Can some one help please?

Minimize Somme of X(ik(i)) for i=1 to k

subject to:

X(ik)- T(ijk) >= X(ih)
X(pk)- X(ik)+ H *[1-Y(ipk)] >= T(pqk)
X(ik)- X(pk)+ H *[Y(ipk)] >= T(ijk)
X(ik)>=0
Y(ipk)= 0 or 1
