چکیده

Predicting the final folded structure of protein molecules and simulating their folding pathways is crucial importance for designing viral drugs studying diseases such as Alzheimer's at molecular level. To this end, letter investigates problem conformation prediction under constraint avoiding high-entropy-loss routes during folding. Using well-established kinetostatic compliance (KCM)-based nonlinear dynamics a molecule, formulates pointwise optimal control synthesis cast quadratic program (QP). It shown that KCM torques in literature can be utilized defining reference vector field QP-based generation problem. The resulting torque inputs will close to KCM-based guaranteed constrained by predetermined bound; hence, are avoided while energy molecule decreased.

Prediction of protein side-chain conformation by packing optimization.

We have developed a rapid and completely automatic method for prediction of protein side-chain conformation, applying the simulated annealing algorithm to optimization of side-chain packing (van der Waals) interactions. The method directly attacks the combinatorial problem of simultaneously predicting many residues' conformation, solving in 8 to 12 hours problems for which the systematic search...

Simulation-based Optimization for Nonlinear Optimal Control

Optimal control of systems with complex nonlinear behaviour such as steady state multiplicity results in a nonlinear optimization problem that needs to be solved online at each sample time. We present an approach based on simulation, function approximation and evolutionary improvement aimed towards simplifying online optimization. Closed loop data from a suboptimal control law, such as MPC base...

Improved Optimization Process for Nonlinear Model Predictive Control of PMSM

Model-based predictive control (MPC) is one of the most efficient techniques that is widely used in industrial applications. In such controllers, increasing the prediction horizon results in better selection of the optimal control signal sequence. On the other hand, increasing the prediction horizon increase the computational time of the optimization process which make it impossible to be imple...

An Inexact Sequential Quadratic Optimization Algorithm for Nonlinear Optimization

We propose a sequential quadratic optimization method for solving nonlinear optimization problems with equality and inequality constraints. The novel feature of the algorithm is that, during each iteration, the primal-dual search direction is allowed to be an inexact solution of a given quadratic optimization subproblem. We present a set of generic, loose conditions that the search direction (i...

Quadratic reformulations of nonlinear binary optimization problems

Very large nonlinear unconstrained binary optimization problems arise in a broad array of applications. Several exact or heuristic techniques have proved quite successful for solving many of these problems when the objective function is a quadratic polynomial. However, no similarly efficient methods are available for the higher degree case. Since high degree objectives are becoming increasingly...
