FCBO——概念格生成算法
代码说明：
This program computes intents of all formal concepts in an object-attribute data set (a formal context), i.e. the algorithm computes all maximal submatrices of a boolean matrix which are full of 1’s. The program implements FCbO, a fast algorithm based on Kuznetsov’s CbO with improved canonicity test. The INPUT-FILE is in the usual FIMI format: each line represents a transaction or an object and it contains of a list of attributes/features/items. If the INPUT-FILE is omitted or if it equals to ‘-’, the program reads the input form the stdin. The OUTPUT-FILE has a similar format, each line represents one intent (itemset), where numbers indicate attributes in the intent (itemset). If the OUTPU
