Shadow testing is a useful way to de-risk algorithm rollout and build confidence in deploying changes to production systems. We take a look at the what, why, when, and how: https://www.nextmv.io/blog/what-is-shadow-testing-for-optimization-models-and-decision-algorithms

What are some good blogs/newsletters to follow related to Analytics/Data Science/Operations Research?

Any suggestions?

TDS and some other medium blogs seem very cluttered nowadays. It is quantity over quality for them but I am looking for the opposite.

For OR, I follow these two blogs:
1. Yet another math programming consultant
2. OR in an OB world

Any suggestions?

Is there any company who actually uses Jump (https://jump.dev/JuMP.jl/stable/) i.e. scalable MIPs in #julialang ?

I have mostly used #rstats for Mathematical Optimization. But might have to move over to #python sooner or later.

Though, the library I have used in R, was massively influenced by Jump Julia. But sadly, no one uses R for Operations Research.

Starting a new newsletter for Data enthusiasts: The Data Voyage.

In this newsletter, I will share with you my insights and experiences on topics such as statistics, operations research, data analysis, and more. I will also showcase some of the cool projects that I am working on or learning from.

I hope you will join me on this journey of discovering the power and beauty of data.

Don’t miss the first post this Saturday. Subscribe for free now!

Our latest release roundup: https://www.nextmv.io/blog/release-roundup-batch-experiments-deeper-app-visibility-and-sample-decision-apps

→ Batch experiments: Will the updated model output shorter routes?
→ Naming and searching runs: What was the input that produced z-shaped routes?
→ Sample decision apps: Point-and-click exploration of app setup and tests

"Troubleshooting without testing is complicated. These are plans that drive real-world activities with real people involved...It's hard to have confidence in your outcomes if you don't have testing in place." --> https://youtu.be/ffS4MTKxZwM

Is optimization a solved problem? How do machine learning, AI, and optimization coexist? What are the most common industry applications of OR today?

We'll ask Karla Hoffman on Wednesday, January 18. Join us: https://www.nextmv.io/videos/in-conversation-with-karla-hoffman-about-optimization-and-operations-research

We hope to see you there!

@evannakita @irisvirus Perhaps the car ferry industry knows some #OperationsResearch things about varying ratio of passengers with cars to passengers without cars.

Na bitte: da ist das Ding:
https://zeybringtbei.de/blog/fix-and-optimize/
Wird zukünftig mal mit einem seriösen MIP als Grundlage aktualisiert. #datascience #operationsresearch #ortools #python

Fix and Optimize mit den Google OR Tools und maximaler Flexibilität -in the making-
Mit Fix and Optimize kann man auf einen OpenSourceSolver zurückgreifen und trotzdem passable Ergebnisse erzielen.

With “the holidays” approaching, a pro-environmental shopping tip:

If you’re shopping online, buy things early & get standard shipping instead of expedited. For expedited, companies may ship via air and/or use trucks that are mostly empty. With standard shipping, companies can have more efficient shipping logistics, resulting in less energy consumption.

Or just walk/bike/transit to the store!

The #OperationsResearch efforts to build the #Amazon Air network are truly amazing.
But the tremendous externalities (e.g., emissions) of the often unnecessary one-day delivery still remain.
