[How To Prompt @HowToPrompt__]

Chinese researchers have developed the best shortest-path algorithm in 41 years!

Dijkstra’s Algorithm has been the undefeated king of the shortest path for over 40 years.

Whether you’re using Google Maps, booking a flight, or routing internet packets, Dijkstra is the engine running in the background.

Since 1984, textbooks have taught that its efficiency was hit by a "sorting barrier."

To find the shortest path, you have to sort the points by distance. And sorting has a mathematical floor you can’t cross.

Until now.

A research team from Tsinghua University just published a paper that shatters the 41-year-old record.

They proved that Dijkstra is not optimal.

By combining the logic of the Bellman-Ford algorithm with a revolutionary "recursive partial ordering" method, they figured out how to find the path without fully sorting the nodes.

The results are a massive shift in theoretical computer science:

- The first deterministic improvement to the Single-Source Shortest Path (SSSP) problem since 1984.

- A new time complexity of $ O(m \log^{2/3} n)$, officially beating the long-standing $ O(m + n \log n)$ limit.

- On massive sparse graphs (like the web or global logistics), this means finding the best route significantly faster than previously thought possible.

For four decades, the greatest minds in algorithms believed this limit was absolute.

Last year, even the legendary Robert Tarjan won an award proving Dijkstra was "optimally efficient" at sorting distances.

Tsinghua’s answer? Stop sorting.

The world’s most settled problem is suddenly wide open again.

If we can break a 40-year-old law in basic graph theory, what other "impossible" speed limits are waiting to be crushed?

LENDA DO ALECRIM ☘️
Dizem que quando a Sagrada Família fugiu para o Egito com Maria levando em seus braços o menino Jesus ,as flores do caminho iam-se abrindo à medida que eles passavam por elas. O lilás ergueu seus galhos orgulhosos e emplumados, o lírio abriu seu cálice . O alecrim sem pétalas nem beleza , entristeceu lamentando não poder agradar ao menino . Cansada, Maria parou à beira do rio e enquanto a criança dormia , lavou suas roupinhas . Em seguida olhou em redor , procurando um lugar para estendê-las .
-- O lírio quebrará com o peso e o lilás é alto demais .
Colocou-as então sobre o alecrim e ele suspirou de alegria , agradeceu de coração a nova oportunidade e as sustentou ao sol durante toda a manhã .
-- Obrigada , gentil alecrim ! disse Maria
--Daqui por diante ostentarás flores azuis para recordar a cor do manto que estou usando . E não são apenas flores que te dou em agradecimento , mas todos os galhos que sustentaram as roupas do pequeno Jesus serão aromáticas .
" Eu abençoo folha, caule e flor , que a partir deste instante terão o aroma de Santidade e emanarão alegria "

Stanford has released Prof. Manning's NLP course for free (!!!) on Youtube if you are interested in diving deeper into NLP.

It starts with the very basic word2vec and expends to:

-> Domain adaptation for supervised sentiment
-> Retrieval augmented in-context learning
-> Advanced behavioral evaluation
-> Analysis methods
-> More NLP methods

Happy A.B.L <Always Be Learning> y'all!

ChatGPT has changed software development!

However, 68.1% of Software Engineers still don't use it.

As a CTO, I'm telling my teams to use ChatGPT in their daily work to increase both velocity and quality.
