Cloud Pak for Data (and its managed "as a Service" version on IBM Cloud) has a command-line client. Let's see how we can use it in a #bash script to send an LP file and have it solved on the cloud. xavier-nodet.medium.com/send…… #cloudpakfordata #decisionoptimization

Send an LP file from command-line to WML using cpdctl

To facilitate the handling of Cloud Pak for Data (CPD) clusters, the CPD team created a command-line client named cpdctl…

There are simple ways to reduce memory consumption when solving your LPs (or the root node of your MIPs) with #CPLEX xavier-nodet.medium.com/cple…

CPLEX usage of RAM when solving continuous models

The memory consumption while solving a model with CPLEX (as with any similar solver) can sometimes be an issue. The amount of RAM…

With #CPLEX, dealing with a MIP that produces too many nodes for the RAM you have may be as simple as « set mip strategy file 3 » xavier-nodet.medium.com/cple…

CPLEX memory usage for MIPs

We’ve seen in a prior post how to deal with memory when solving an LP.

They told me to "Make History" at @PdxInteractive so I rewrote git history and force pushed on @HOI_Game's main branch. I'm not sure that's what they meant...

It is a shame to cherry pick data to serve an ideology. In math 3 women out of 38. The overall proportion is not 80% of women. Ans this is not about Aggregation either.
Professor Sandra Lapointe (ACCOUNT PAUSED)@mslapointe19 Aug 2020
Paris ENS is France’s top school and agregation there is highly competitive. This year, due to COVID they cancelled the orals, only had the (anonymous) written exam. As a result ~80% of successful candidates were women. 8-0. Eighty. Women usually represent ~40% of ENS agrégés

I'm no legal expert but... is this whole "need to be connected to X" just a loophole to circumvent GDPR? Article 7.3 clearly states "only data strictly necessary for the service should be mandatory". Are they trying to get around that by asking to link to a social account?

"AI competition boils down to a simple technical triad: data, algorithms, and computing power." Wrong! It also requires human expertise that is in short supply to develop & apply foreignaffairs.com/articles/… via @ForeignAffairs

The U.S. Has AI Competition All Wrong

Computing power, not data, is the secret to tech dominance.

It is a real pleasure to announce that CPLEX users group on LinkedIn, has outreached 2500 members. A real challenge for a niche product. Take a look at the group and join us ^_^ linkedin.com/groups/3973271/
