THUEE five experimental data and algorithms: the construction of roads in a regional plan that has a road between the villages can be accessible to all. Assuming that all new road construction is a direct connection between two villages, in addition to the villages have no meeting point, and all roads are two-way traffic, there is no one-way street. Please design an algorithm to solve the following problems: 1 gives a minimum construction cost of the program (if it exists) 2 to determine the lowest cost solution is unique. .. If the only gives a minimum cost in addition to the program options (if it exists) otherwise, given the other options for the lowest cost.
