A modified subgradient extragradient method for solving monotone variational inequalities
In the setting of Hilbert space, a modified subgradient extragradient method is proposed for solving Lipschitz-continuous and monotone variational inequalities defined on a level set of a convex function. Our iterative process is relaxed and self-adaptive, that is, in each iteration, calculating two metric projections onto some half-spaces containing the domain is involved only and the step siz...
متن کاملFeasible Modified Subgradient Method for Solving the Thermal Unit Commitment Problem as a New Approach
The Lagrangian relaxationLRbased methods are commonly used to solve the thermal unit commitment UC problem which is an important subject in power system engineering. The main drawback of this group of methods is the difference between the dual and the primal solutions which gives some significant problems on the quality of the feasible solutions. In this paper, a new approach, feasible modified...
متن کاملBarrier subgradient method
In this paper we develop a new primal-dual subgradient method for nonsmooth convex optimization problems. This scheme is based on a self-concordant barrier for the basic feasible set. It is suitable for finding approximate solutions with certain relative accuracy. We discuss some applications of this technique including fractional covering problem, maximal concurrent flow problem, semidefinite ...

Convergence of a simple subgradient level method
We study the subgradient projection method for convex optimization with Brr ann-lund's level control for estimating the optimal value. We establish global convergence in objective values without additional assumptions employed in the literature.
