Looking forward to playing with this Jupyter notebook on the Adaptive Partition Method for SP. Thank you @borelian for making APM so easily accessible to our SP community!
Eduardo Moreno@borelian4 Mar 2022
LandS (@JeffLinderoth et al, 2006) has been a classical benchmark instance on Stochastic Programming. We now know its *exact* optimal value: 225.6294001. Take a look at github.com/borelian/LandS_ex… for a simple and instructive Jupyter notebook explaining how to use APM to prove this.

Hope to see you at #IOS2022 in Greenville SC! New submission deadline: Jan. 31. Picture was taken on Christmas Eve, in March it will be even more gorgeous!
Cole Smith@j_cole_smith31 Dec 2021
The @InformsOS Opt Soc conference in G'ville, SC, 3/13-3/15 is still a go, fully in-person. With the ongoing COVID-19 crisis, we know you may need more time to decide if you can travel. Thus, we're extending the IOS2022 submission deadline until Jan 31. Hope you can join us!
