      I checked online blog by one of the "opponents". He teaches to measure code performance using c# http://DateTime.Now  and implements A* using dozens of classes. It will be very to hard for both of you to find common language. Because he lives in very different world from us.

      I'm actually interested how you could implement A* using dozens of classes. I recently implemented it for a small 2D experiment and it ended up being a single function spanning no more than 50 lines of code.

      This is amazing! A* is normally like thirty lines of code :) "Modern" programming is so insane.

          Yeah, look at the amount of code in the Duration.cs file.

          it's not strictly insane, they're just not "implementing an algorithm". What they're doing is "implement a new semantic universe that happens to also include the algorithm". And now every downstream problem is /also/ a problem of semantic interference.

          Replying to @skore_de @cmuratori and

          Why are they like that? I think it's two reasons a) the thinking that most algorithms are already implemented somewhere, you just have to load the library b) they're implementing their own journey of understanding a problem instead of the result of that journey.

          "For a comprehensive overview of how the A* algorithm works I recommend this interactive article by Red Blob Games." I wonder why he's not recommending his own code
