Hi, I've never heard of that before. Do you have a picture at hand what this actually is? I also only read half of your posting because I somehow lost it. My gut feeling tells me that all those stitches can be represented in a 2d array consisting of -1, 0 and 1 which represent "down", "nothing", "up". All remaining things you tell us are probably linear constraints, or maybe can be made to be (distances are not linear). Hence, this is a MILP and you can use Sage's MixedIntegerLinearProgram class. You will also need to install a solver for problems of a bigger size, like coin-or/cbc.
