official code for http://journals.aps.org/pre/abstract/10.1103/PhysRevE.89.022142 Extended Parrondo's game and Brownian ratchets: Strong and weak Parrondo effect by Degang Wu and Kwok Yip Szeto
complete Mathematica code to reproduce Figures 1-8 in the said paper. Code for reproducing Figure 9 will come soon.
Since I use lots of Greek letters and subscripts symbols, the two .m files containing the functions are unreadable in plain text. Viewing them in Mathematica's notebook program is highly recommended.
