Efficient Rank Minimization to Tighten Semidefinite Programming for Unconstrained Binary Quadratic Optimization
Roman Pogodin, Mikhail Krechetov, Yury Maximov
We propose a method for low-rank semidefinite programming in application to the semidefinite relaxation of unconstrained binary quadratic problems. The method improves an existing…

Quadratic Programming Approach to Fit Protein Complexes into Electron Density Maps
Roman Pogodin, Alexander Katrutsa, Sergei Grudinin
The paper investigates the problem of fitting protein complexes into electron density maps. They are represented by high-resolution cryoEM density maps converted into overlapping m…
