The format of the input file "input.txt" is as follows (see the sample file): Line 1: the supposed cardinality of the scenario. Line 2: the noise level (see description of test 3 in the paper). Lines 3-66: the given distributions on leaves (the leaves are numbered left to right). The format of the output file "artif.log": - Run parameters; - Done work stages; - The edges of the found scenario (notation i.j means the edge on the i-th level from the root having the j-th number from the left). - The distributions of the scenario at all vertices (the root is "vertex 0"; "vertex i.j" means the end of the edge i.j from the root). The program "artif.exe" is run without any arguments in command line and works in the background. The run time of the program with the scenario cardinality 10 is about 50 minutes. During the process the lines "done 0 of 6", "done 1 of 6", "done 2 of 6", "done 3 of 6", "done 4 of 6", "done 5 of 6", "done 6 of 6" subsequently appear in the file "artif.log", and finally the found scenario is output.
