Solvers:

• lib/ConvexPolygonSolver.cs — for convex problems
• lib/SolutionSpecExt.cs — implementation of the solution folding
• lib/ProjectionSolver/UltraSolver.cs — for simple non-convex problems (tries to compose initial square perimeter with rational segments from a problem and then restore other points)
• lib/Constructor/ConstructorSolver.cs — for other simple non-convex problems (tries to construct the initial square from polygons of the given silhouette)
• lib/Visualization/ManualSolving/ManualSolverForm.cs — UI for manual problem solving (you can do several reflections and then apply the convex solver)
• lib/Visualization/Visualizer.cs — visualizer of all problems with ability to open ManualSolverForm
• lib/SolutionPacker.cs — optimizer of the solution size

Problem generators:

• lib/D4Problem.cs — generator of problems not solvable in 3 dimensions.
• lib/Problems.cs — generator of some other simple problems.

Infrastructure:

• TimeManager/ — throttler for api calls
• AutoSolver/ — daemon that downloads new problems and runs solvers.
• problems/ — directory with problems, solutions and responses of solution/submit api call

Yes, we gain a lot of points via a semi-automatic solver. A human needs to do several folds to make a figure convex, and then the convex solver do the rest.

We found some inspiration in these articles:

• Folding Flat Silhouettes and Wrapping Polyhedral Packages: New Results in Computational Origami
• The Polygon Containment Problem
• Articles by Robert J. Lang

Also, Wolfram Alpha was useful in manual computations.
