A new algorithm for enumeration of minimum cutsets of graph by branch addition
... problem can be solved easily. For this approach, above algorithm should be changed as follows: 1. Algorithm should start with an output node. 2. The node set made for minimum cutset enumeration, ... other algorithms should be searched in such cases. Some of these algorithms, which are based on finding minimum paths, need a large size of memory and more computation time. Thus, these algorithms ... many times the algorithm should be performed and in each repetition of the algorithm, only one of them is considered as output node of the graph.
