Comment on “Combined heat and power economic dispatch by mesh adaptive direct search algorithm” by Sadat Hosseini et al. [Expert Syst. Appl. 38 (2011) 6556–6564]

Recently, an interesting approach for combined heat and power economic dispatch was proposed by Sadat Hosseini et al. [Expert Syst. Appl. 38 (2011) 6556–6564]. However, there are several simple mistakes in the solution results and the references. In this note we will present a corrected results and references given therein. Furthermore, it is shown that the studied cases are not strong enough to validate the presented algorithm for combined heat and power economic dispatch problem.
