#labyrinth

“Unmoored from human reasoning, and especially those features of human reasoning often called ‘common sense’, learning algorithms won’t trap us in bubbles.

"A bubble has a coherent, predictable structure.

"Netflix’s recommendations are more like a labyrinth built by an alien who doesn’t know they’re supposed to have exits.

"There’s no recognisable logic to them at all."

"What is a Labyrinth to a Topologist?

"We arrive at the most fascinating application. A labyrinth does not look like a polyhedron, but topology taught us to abstract. What is a labyrinth in its purest essence? It is a graph: a set of nodes (intersections) connected by edges (corridors). This idea of reducing a complex map to a connectivity graph is, in fact, the very origin of topology, used by Euler in 1736 to solve the Königsberg Bridges problem. A labyrinth is, therefore, a topological space that we can analyze.

"The Algorithm as a Topological Explorer

"In our final simulation, we do not have a static labyrinth, but a Genetic Algorithm (GA) trying to solve it. A GA mimics biological evolution: it creates a “population” of hundreds of possible paths (the “individuals”); evaluates how “fit” they are (how close they get to the exit); and the best individuals “reproduce” (their paths are combined) and “mutate” (small random changes).

Generation after generation, the population evolves toward an optimal solution. Crucially, the GA does not explore just one path, but deploys an “exploration network” that covers vast areas of the labyrinth simultaneously. We can measure the shape of that network."

Ha!

The treeline in the bottom centre of this image obscures one of my work-in-progress painted Labyrinths located beside the children's playground.

I went down to the Kaymaklı underground city. It is an underground labyrinth built to protect refugees from enemies where thousands of people used to live. ​Once you are inside there is no turning back it is a one way route. I had to crawl in some places because it was very narrow and there were no stairs (Thanks to my Adidas Terrex I was able to walk and crawl without any problems) ​The real issue was claustrophobia(which I don't have anyway) many people couldn't even enter because of panic attacks. Some passages were only 70 to 60 cm high and even though I am very petite my shoulders were touching the walls. I could really feel the stones all around me, so you can imagine how narrow it was. Imagine the soldiers who got trapped there with muscular build and heavy armor, they probably all lost their way out. (I have a video of the crawl that I might share later though uploading videos here is a bit problem) Sometimes you get stuck inside just waiting for other people to move. I definitely do not recommend it to claustrophobic people. (We went down about 20 meters)

​I specifically wanted to go down there to test myself before my next trip to Egypt. My dad told me I couldn't enter the pyramids, so I went 20 meters underground to prove to myself that I could. And I did it 😏 At least now I am ready for Egypt it was a great warm up. This place was one of my favorite in there.

Another surprising fact is, the underground city was airier and felt much more spacious than above ground
