Sunshine and transit routing

It’s one of the first sunny days of the year and a perfect one for sitting outside on the balcony and relaxing with a good book reading a stack of research papers about transit routing algorithms.

Eventually the app will have automatic routing but nothing I’ve read about so far solves the problem in a way I can use. It’s a hard problem even when you have huge servers, it’s even harder on a processor- and memory-constrained device like a phone. But I’ll get there, my head is full of ideas and even if these papers don’t solve the problem they help by planting even more ideas.
