Submodular Optimization with Submodular Cover and Submodular Knapsack Constraints [PDF]

open access: yes, 2013
We investigate two new optimization problems -- minimizing a submodular function subject to a submodular lower bound constraint (submodular cover) and maximizing a submodular function subject to a submodular upper bound constraint (submodular knapsack ...

Identifying representative sequences of protein families using submodular optimization [PDF]

open access: yesScientific Reports
Identifying representative sequences for groups of functionally similar proteins and enzymes poses significant computational challenges. In this study, we applied submodular optimization, a method effective in data summarization, to select representative
