This is a very handy doc indeed. I'm not sure though that examples on #29 - #31 address the problem I'm looking into. Namely, I need minimum tracking error with explicit constraint on the number of stocks that is lower than in the benchmark portfolio. Coleman, Li, and Henniger (2004) state that it's NP-hard problem and review a few heuristic methods. Is there one implemented in PortfolioAnalytics? Thanks much!
