ε-approximate solutions in multiobjective optimization
Zhongfel. Li, Shouyang Wang · Optimization · 1998
In this paper. we are concerned with approximate solutions to a multiobjective and nonconvex programming problem. A new concept of ε-proper efficiency is :ntroduced. A few of necessary and/or sufficient conditions for an ε-efficient solution (:.esp.. an ε-properly efficient. an ε-weak efficient solution) are derived via scalarization and an alternative theorem. The resultsin this paper generalize and refine some known results in multiobjective optimization.
