c語言編譯器，跨平臺，4.2版本
lcc version 3.x is described in the book "A Retargetable C Compiler:
Design and Implementation" (Addison-Wesley, 1995, ISBN 0-8053-1670-1).
There are significant differences between 3.x and 4.x, most notably in
the intermediate code. For details, see

本文件為用C語言實現(xiàn)的可實現(xiàn)廣義異或問題的bp神經(jīng)網(wǎng)絡(luò)算法。該問題是對標(biāo)準(zhǔn)異或問題的推廣。在標(biāo)準(zhǔn)異或問題中，輸入X1和X2取離散量-1或+1，在廣義異或問題中，輸入（X1,X2）可以在區(qū)間[-1，+1] X [-1, +1]內(nèi)任意取值，而輸出為Y=sign(x1,x2)，其中sign()為符號函數(shù)，在區(qū)間[-1，+1] X [-1, +1]內(nèi)隨機產(chǎn)生500個訓(xùn)練樣本.本程序用標(biāo)準(zhǔn)BP網(wǎng)實現(xiàn)該分類問題.
