From: SparseRNAfolD: optimized sparse RNA pseudoknot-free folding with dangle consideration
Graphical representation of the sparsified versions of the recursions: \(W^p\), \(W\!M^p\), and \(W\!M^2\). The notation for these figures is as follows: a solid horizontal line signifies the RNA sequence, a solid arc denotes base pairs, and dashed arcs represent regions. Fixed endpoints of a region are depicted by red circles, while blue squares indicate unpaired elements used for boundary determination
