Convex preference cone-based approach for many objective optimization problems
(Elsevier, 2018-03)
Many objective optimization problems have turned out to be a considerable challenge for evolutionary
algorithms due to the difficulty of finding and visualizing high-dimensional Pareto frontiers. Fortunately,
however, the ...
Multiple allocation hub interdiction and protection problems: model formulations and solution approaches
(Elsevier, 2018-03-29)
In this paper, we present computationally efficient formulations for the multiple allocation hub interdiction and hub protection problems, which are bilevel and trilevel mixed integer linear programs, respectively. In the ...
A review on bilevel optimization: from classical to evolutionary approaches and applications
(IEEE, 2018)
Bilevel optimization is defined as a mathematical
program, where an optimization problem contains another optimization
problem as a constraint. These problems have received
significant attention from the mathematical ...
Alternate second order conic programming reformulations for hub location with capacity selection under demand uncertainty
(Indian Institute of Management Ahmedabad, 2018)
In this paper, we study the single allocation hub location problem with capacity
selection in the presence of congestion at hubs. Accounting for congestion at hubs leads
to a non-linear mixed integer program, for which ...
Uncertainty handling in bilevel optimization for robust and reliable solutions
(World Scientific, 2018)
Uncertainties in variables and parameters cause optimization problems to move away from globally-optimal and uncertain solutions. Practitioners resort to finding robust and reliable solutions in such situations. Bilevel ...
