The proceeding paper Solving Electric Market Quadratic Problems by Branch and Fix Coordination Methods has been published by Springer in the series IFIP Advances in Information and Communication Technology (doi:10.1007/978-3-642-36062-6_51). In this paper the Branch&Fix Coordination methodology is applied to the solution of an specific class of quadratic two-stage stochastic programming problems arising in the field of the electricity market optimization. This work has been supported by the research project grant DPI2008-02153 of the MINECO.
