The Bongard data generator program generates random synthetic data akin to a simplified version of Bongard problems used as benchmarks in ILP. For the ILP version of the Bongard problem,

• Training examples. Each example is a "picture" composed of simple geometrical objects (elements). An object can be one of the three shapes: circle, square and triangle. A triangle may be pointing up or down.
• Background knowledge. The background knowledge provides the shape of each object and their positions relative to one another for each picture.
• Task. The problem is to find a set of clauses that are consistent with a set of positive and negative pictures.

Two restrictions are enforced when the data is generated: 1) Each picture cannot have a pair of partially overlapped objects; 2) All objects must be fully enclosed in the boundary of the picture specified in Configurations.hpp.

The source code of the generator program is available for download from the public Github repository.
