# Research articles on MultiObjective Non-Linear Programming (MONLP)

I'm looking for papers dealing with multi-objective non-linear programming which could help me implement an algorithm to solve my problem.

My problem is :

Maximize $$f(x) = c \cdot x$$, while minimizing $$g(x) = r \cdot x$$, where $$\cdot$$ is the scalar product.

Constrained by $$h_1(x) = \frac{v \cdot x}{p \cdot x} \geq 0.5$$ and $$h_2(x) = b \cdot x = B$$

Given that $$b, c, p, r, v \in (\mathbb{N}^*)^n, B \in \mathbb{N}^*, x \in [0, 1]^n$$

For me, $$n$$ will be in the order of $$1000$$.

I know there is no unique solution so I'm looking for the set of Pareto optimal solutions, therefore I am not interested in scalarizing. I could use interactive methods though.

In Gandibleux, X. (Ed.). (2006). Multiple criteria optimization: state of the art annotated bibliographic surveys (Vol. 52). Springer Science & Business Media., I found in chapter 5 many interactive nonlinear multiobjective procedures explained. According to Kaisa Miettinen, none is better than another and they all have their pros and cons.
