Undecidability and hardness in mixed-integer nonlinear programming

L Liberti - RAIRO-Operations Research, 2019 - rairo-ro.org
We survey two aspects of mixed-integer nonlinear programming which have attracted less
attention (so far) than solution methods, solvers and applications: namely, whether the class …

[图书][B] Euclidean distance geometry

L Liberti, C Lavor - 2017 - Springer
What do clocks, wireless devices, atoms, and submarines have in common? They move: the
clocks move time forward (so to speak), wireless devices usually move on a plane (like an …

Distance geometry and data science

L Liberti - Top, 2020 - Springer
Data are often represented as graphs. Many common tasks in data science are based on
distances between entities. While some data science methodologies natively take graphs as …
