DOI: 10.1016/j.jclepro.2021.126874
Abstract: Abstract Uncertainty surrounding the sources of nonpoint pollution and producer response to prospective policy incentives complicates the nonpoint policy problem. To explain, neither policy-makers nor producers know the exact effect of current and alternative farming… read more here.

DOI: 10.1080/10556788.2021.1977810
Abstract: We consider the standard optimistic bilevel optimization problem, in particular upper- and lower-level constraints can be coupled. By means of the lower-level value function, the problem is transformed into a single-level optimization problem with a… read more here.

DOI: 10.1162/neco_a_01547
Abstract: Abstract This review examines gradient-based techniques to solve bilevel optimization problems. Bilevel optimization extends the loss minimization framework underlying statistical learning to systems that are implicitly defined through a quantity they minimize. This characterization can… read more here.
