A Steepest Feasible Direction Method for Linear Programming. Derivation and Embedding In the Simplex Method [PDF]

Operations Research and Decisions
A feasible direction method for linear programming has been proposed. The method is embedded in the framework of the simplex method, even though it works with non-edge feasible directions.

A Fast and Efficient Adversarial Attack Based on Feasible Direction Method

IEEE Access
It has been shown that deep neural networks can be easily fooled by adversarial examples, which are samples delicately crafted by adding small imperceptible perturbations to the input.

Developing a Boundary Point Method Algorithm for Solving Linear Programming Problems with Feasible Initial Solution [PDF]

مجله مدل سازی در مهندسی, 2019
In this research, SALCHOW algorithm has been developed to solve linear programming problems. In each step SLACHOW moves towards the constrained gradient of the objective function, so that it always remains within the feasible region.

Coordinative Optimization of Emergency Control Based on Constraint Consensus and Differential Evolution in Multi-DC Infeed Power Grid

Zhongguo dianli, 2023
The multi-direct current (DC) infeed power grid faces the risk of system instability after the DC blocking fault. Coordinating multiple emergency control resources can ensure system stability and control economy.

An extension of the method of feasible directions [PDF]

, 1975
In this contribution we are going to discuss the extension of the method of feasible directions[1],[2],[3] to programming problems involving an infinite number of constraints. Problems of this type arise frequently in applications. We shall be working with arbitrary convex approximations instead of with linearizations, simply to emphasize the fact that

Microlens Array Fabrication by Using a Microshaper

Micromachines, 2021
A simple, easy, inexpensive, and quick nonsilicon-based micromachining method was developed to manufacture a microlens array. The spherical surface of the microlens was machined using a microshaper mounted on a three-axis vertical computer numerical ...
