Systems and methods for efficient frontier supplementation in multi-objective portfolio analysis
First Claim
1. A method for multi-objective portfolio optimization for use in investment decisions based on competing objectives and a plurality of constraints constituting a portfolio problem, the method comprising:
- performing a first multi-objective optimization process, based on competing objectives, to generate an efficient frontier of possible solutions;
observing the generated efficient frontier;
based on the observing, identifying an area of the efficient frontier in which there is a gap;
effecting a gap filling process by which the efficient frontier is supplemented in the area of the gap, the efficient frontier being used in investment decisioning.

Abstract
The systems and methods of the invention are directed to portfolio optimization and related techniques. For example, the invention provides a method for multi-objective portfolio optimization for use in investment decisions based on competing objectives and a plurality of constraints constituting a portfolio problem, the method comprising: performing a first multi-objective optimization process, based on competing objectives, to generate an efficient frontier of possible solutions; observing the generated efficient frontier; based on the observing, identifying an area of the efficient frontier in which there is a gap; and effecting a gap filling process by which the efficient frontier is supplemented in the area of the gap, the efficient frontier being used in investment decisioning.

-
performing a first multi-objective optimization process, based on competing objectives, to generate an efficient frontier of possible solutions;
observing the generated efficient frontier;
based on the observing, identifying an area of the efficient frontier in which there is a gap;
