MILANO:Mixed-Integer Linear and Nonlinear Optimizer
MILANO is a Matlab-based solver for mixed-integer linear and nonlinear programming problems.
It uses a branch-and-bound method for handling integer variables, and an interior-point
method for solving the linear and nonlinear relaxations. The warmstarting scheme is
based on the primal-dual penalty framework of Benson and Shanno, as documented
here and here.
MILANO is still in development, but available for testing to the research community. Feel
free to contact me with any questions and bug reports.

- The source for MILANO is available as a gzipped tarball of Matlab .m files. You can download it
here.
- Here is an example for building models to solve with MILANO.
The code is called as [x,fval,exitflag] = milano(f, gradf, g, jac, hessn, intflag, K), where
intflag is a 0-1 array indicating which variables are binary-valued, and K includes information
on the cone, similar to SeDuMi.
