Typos, dude, typos. First off, e is not the same as E, so: Simgmoi[x_?(Length@# == 5 &)] := {1/(1 + e^-x[[1]]), 1/( 1 + e^-x[[2]]), 1/(1 + e^-x[[3]]), 1/(1 + e^-x[[4]]), 1/( 1 + e^-x[[5]])}; Should be: Simgmoi[x_?(Length@# == 5 &)] := {1/(1 + E^-x[[1]]), 1/( 1 + E^-x[[2]]), 1/(1 + E^-x[[3]]), 1/(1 + E^-x[[4]]), 1/( 1 + E^-x[[5]])}; Also, in your initialization statement: init = {W == ( { {0.2, 0.3, 0.1}, {0.5, 0.7, 0.3}, {0.5, 0.2, 0.1}, {0.3, 0.2, 0.6}, {0.7, 0.5, 0.1} } ), e[0] == {0.2, 0.3, 0.4}, r[0] == {0.1, 0.4, 0.5}}; Should be init = {W[0] == ( { ... This should get you going again. I think AccuracyGoal->Infinity is inadvisable, you might want to scale back on your expectations. Daniel
