Realization of a reverse communication algorithm written last year, Tlunetwork.h This header implemented a Tlunetwork template, using a basic BP algorithm, and there are three examples. 1. Classic different or problem http://newsuppy.go.nease.net/xor.rar2, function approximation problem f (x) = 1 sin (pi / 4 * x), x = -2: 0.2: 2 (1) OpenGL version, you need the support of the GLUT toolbox http://newsuppy.go.nease.net/funcapproxogl.rar(2) GDI version http://newsuppy.go.nease.net/funcapproxgdip.rar
