Benchmarking project portfolios using optimality thresholds
Omega, 2021Abstract Risk assessment and selection of project portfolios are carried out under uncertainty, since this process uses historical data that can be adjusted in the future. The problem is whether the decision is still favorable and the level of risk is still acceptable to the investor.

Multiobjective optimization for project portfolio selection
Proceedings of the 14th annual conference companion on Genetic and evolutionary computation, 2012This paper proposes a multiobjective heuristic search approach to support a project portfolio selection technique on scenarios with a large number of candidate projects. The original formulation for the technique requires analyzing all combinations of candidate projects, which is unfeasible when more than a few alternatives are available.

Sparse simplex projections for portfolio optimization
2013 IEEE Global Conference on Signal and Information Processing, 2013We derive efficient sparse projections onto the simplex and its extension, and illustrate how to use them to solve high-dimensional learning problems such as portfolio selection with non-convex constraints. To this end, we study the following sparse Euclidean projections.
