Variational Convexity of Functions and Variational Sufficiency in Optimization

open access: yesSIAM Journal on Optimization, 2023
The paper is devoted to the study, characterizations, and applications of variational convexity of functions, the property that has been recently introduced by Rockafellar together with its strong counterpart. First we show that these variational properties of an extended-real-valued function are equivalent to, respectively, the conventional (local ...

Variations on variants [PDF]

open access: yesProceedings of the 2015 ACM SIGPLAN Symposium on Haskell, 2015
Extensible variants improve the modularity and expressiveness of programming languages: they allow program functionality to be decomposed into independent blocks, and allow seamless extension of existing code with both new cases of existing data types and new operations over those data types.
