@sanef_client j’aimerais bien payer mon péage mais impossible avec votre site qui est en maintenance depuis au moins 11h ce matin. Quand le retour en ligne est-il prévu? J’aimerais bien éviter la surcharge

@m_samovar J’ai eu un prof de maths au collège qui rendais les copies en disant les notes à voix haute en ordre décroissant de 17 à 0 puis les copies entre 18 et 20… Un stress incroyable à chaque fois…

I truly and unironically want drivers to demand that all forms of human mobility pay their fair share for the infrastructure we use. Biklings pay for bike lanes, pedestrians pay for sidewalks, buses pay for bus lanes, drivers pay for car lanes.

Really. No more pretending.

@shahrukh_chem Indeed, my initial message was pretty vague :) looking to something introducing simplex, branch-and-bound, column generation, benders decomposition, (meta)-heuristic approaches, constraint programming, graph algorithms (does not need to be everything in a single book)

Hello Operation Research Twitter :)
I am looking for an introductory book to operation research, for someone with a strong background in programming but with no knowledge of optimization techniques. Do you have any recommendations?

[Renaud Masson @renaud_masson]

@shahrukh_chem Thanks! I am a big fan of Model Building in Mathematical Programming. However I was looking more into something covering solution methods rather than modelling (if I remember correctly some solution methods are shortly covered but the focus lies more on modelling in this book)

Kindness Is Always The Right Response

- What gets the best part of your day? Is it your morning coffee, your favorite song, or a hug from a loved one?
- Kindness is always the right response. No matter what someone says or does to you, you can choose to be kind and respectful.

Thread pas drôle du tout.

On a beau savoir qu'on arrive à un point de non retour dans la degradation du système de santé, encore plus nous les soignants.
Mais aujourd'hui je l'ai vécu de près.

j'ai choisi de faire confiance à votre service de livraison à domicile en dépit des avis très négatifs sur internet.

C++ hot take: Most instances of std::pair would be better if replaced with a simple struct with two named members (& no methods)

This generalizes to tuples (& other langs!). Outside of templates, or when the size is variable, it's almost always better to just name the members.

How can you make sure that transport and maintenance plans are in sync with production scheduling? Many companies plan these activities separately, which may lead to incompatible plans. So how can you solve this? Supply Chain Consultant Boone explains how it’s done.

@smlpth Kirby a un mode co-op plutôt chouette qui s’adapte bien à une différence de niveau entre deux joueurs (ça marche bien avec mon 9 ans et ma 7 ans). Si tu veux vraiment que les 3 puissent jouer en même temps “Just Dance” est super sympa (et en plus c’est physique ;) )
