Penalized variable selection procedure for Cox models with semiparametric relative risk

open access: yes, 2010
We study the Cox models with semiparametric relative risk, which can be partially linear with one nonparametric component, or multiple additive or nonadditive nonparametric components.

Logarithmic penalty function method for invex multi-objective fractional programming problems

open access: yesJournal of Taibah University for Science, 2020
In this paper, a new logarithmic penalty function method is used for solving nonlinear multi-objective fractional programming problems (MOFPP) involving invex objectives and constraints functions with respect to the same function η.

On a Class of human development index measures [PDF]

open access: yes
Using Minkowski distance function we propose a class of Human Development Index measures. Special cases of this turn out to be the popularly used linear average method as also a newly proposed displaced ideal method. Two measures of penalty are suggested.

Nonlinear programming without a penalty function or a filter [PDF]

open access: yes, 2007
A new method is introduced for solving equality constrained nonlinear optimization problems. This method does not use a penalty function, nor a barrier or a filter, and yet can be proved to be globally convergent to first-order stationary points. It uses

A Class of Exponential Penalty Functions [PDF]

open access: yesSIAM Journal on Control, 1974
A class of penalty functions where the trial solutions may be interior or exterior to the feasible region of a nonlinear program is developed. Conditions under which the trial solutions become feasible are presented and a convergence rate is established.
