Niantic (of Pokemon Go and Harry Potter Wizards Unite) have Ingress as their first game. Gameplay is very basic compared to the other games, which goes a long way to explaining why I put Ingress down for a long time when Pokemon Go started.
Package Odin has gone live on CRAN with version 1. It makes some stuff with deSolve a little easier: - Defining a set of ODEs looks a bit easier - it’s easier to change parameters - it can write its own C code for when you’ve got a massive set of ODEs and the efficiency helps.
