Portfolio selection is an important but complicated topic in finance. This paper uses quadratic and integer programming methods (dual ascent, branch-and-bound) to solve portfolio selection problems involving risk (variance), return, multiple restrictions (constraints), and proposals that are linked in various ways. A detailed description of the methodology is provided, along with extensive computational results on a variety of problems.
