This C code conducts deterministic iterations of the exact recursion equations presented in the Model section of "Evolution of sexual cooperation from sexual conflict" by Servedio, Powers, Lande and Price.  The code produces a two-dimensional grid with any parameters of choice on the x and y axis.  Examples can be found in Figures 2c, 3c and 4 of the main text as well as many similar figures in the Supplementary Material.  A sample parameter file is included as well.
