To Tell the Truth

truth_data  truth_solutions 
*Note: During the contest, an issue was discovered with the data for Mobilization. Certain cases had collinear points, which caused answers to be numerically unstable. The judge solutions all produced a wrong answer in certain cases (and all the same wrong answer). The degenerate cases were removed.
