The goal of this study is dedicated to the research on the fixed point iterative algorithm for solving the common fixed point problems in Hilbert spaces. In this study, we first propose the hybrid and shrinking projection algorithms of two different nonexpansive mappings for a class of algorithms with two iterative sequences to solve the common fixed ...

Two-direction Subgradient Method for non-differentiable Optimization Problems
One more search direction is introduced into the subgradient method for non-differentiable optimization problems to enhance the speed of convergence. The proposed algorithm generates a point which is strictly closer and forms a more acute angle to the ...

Multi-Objective Optimization Design through Machine Learning for Drop-on-Demand Bioprinting
Drop-on-demand (DOD) bioprinting has been widely used in tissue engineering due to its high-throughput efficiency and cost effectiveness. However, this type of bioprinting involves challenges such as satellite generation, too-large droplet generation ...

Linear Interpolation Method for Adversarial Attack [PDF]
Deep neural networks exhibit significant vulnerability in the face of adversarial examples and are prone to attacks.The construction of adversarial examples can be abstracted as an optimization problem that maximizes the objective function.How-ever ...

A subgradient projection method for quasiconvex minimization
Abstract In this paper, a subgradient projection method for quasiconvex minimization problems is provided. By using strong subdifferentials, it is proved that the generated sequence of the proposed algorithm converges to the solution of the minimization problem of a proper, lower semicontinuous and strongly quasiconvex function (in the sense of

Revisiting Subgradient Method: Complexity and Convergence Beyond Lipschitz Continuity
The subgradient method is one of the most fundamental algorithmic schemes for nonsmooth optimization. The existing complexity and convergence results for this method are mainly derived for Lipschitz continuous objective functions.
