Methods of Feasible Directions: A Review

Applied Optimization, 2000
Since the theoretical basis for the method of feasible directions (MFD) was originally developed by Zoutendijk in 1960’s, several basic variations and modifications of MFD were proposed and investigated. Even though faster algorithms for solving nonlinear programming problems exist, MFD has never been abandoned because of several important advantages ...

Feasibility of self-directed learning in clerkships

Medical Teacher, 2013
Self-directed learning has been well described in preclinical settings. However, studies report conflicting results when self-directed initiatives are implemented in clinical clerkships.To explore the feasibility of self-directed learning stimulated by clinical encounter-cards (CECs) in clinical clerkships.Two focus groups of year-four and year-five ...

Feasibility of Symbolic Directions on Prescription Labels

Drug Intelligence & Clinical Pharmacy, 1979
This project presents the results of a study designed to evaluate the usefulness of graphic labels in assisting functionally illiterate patients to understand how and when to take medication. The project's results indicate that comprehension of symbolic directions did not increase as rapidly as comprehension of typed directions. Symbolic directions did,

A Drivable Method of Feasible Directions

SIAM Journal on Control, 1973
This paper presents a feasible directions algorithm for solving a general nonlinear programming problem. The algorithm is characterized by the fact that it is parametrized by functions. One may, through proper choice of the parametrizing maps, model the algorithm to optimize its behavior with respect to classes of problems.

Feasibility of direct-biogas SOFC

International Journal of Hydrogen Energy, 2008
Abstract Direct feeding of real biogas generated in a methane fermentation reactor to SOFC was tested by using Ni–ScSZ cermet as an anode material. At the operating temperature of 1000 °C, cell voltage above 0.9 V (at 200 mA cm −2 ) was stably obtained over 50 h without carbon deposition showing direct-biogas SOFC is feasible.

The Auxiliary Problem for Feasible Directions

AIAA Journal, 1975
The present work compares the computational efficiency of two means of determining a direction vector S at constraint boundaries and demonstrates the advantages of using the alternative that formulates the S-determination subproblem with a single quadratic constraint, which in turn can be cast as a special linear problem and solved directly.
