RNA molecules whose secondary structures contain similar substructures often have similar functions. Therefore, an important task in the study of RNA is to develop methods for discovering substructures in RNA secondary structures that occur frequently (also referred to as motifs). In this paper, we consider the problem of computing an optimal local(More)
The kinematic characteristic and energy of the conformations of a protein determine its motion and structure. Different conformations of the same protein have different amounts of energy. The protein favors the conformations whose energy levels are low because in that case, the conformations would be more stable. The energy level can be modelled as a(More)
