Detailed Description

Memory efficient ensemble interaction predictor that uses a heuristic to find the mfe or a close-to-mfe interaction.

To this end, for each interaction start i1,i2 only the optimal right side interaction with boundaries j1,j2 is considered in the recursion instead of all possible interaction ranges.

This yields a quadratic time and space complexity.
