Great talk by @hirokisayama about the history of artificial life.

Someone said to me at an Artificial Life conference: "You *have* to read this book, it's about what you do!" (I got into Artificial Chemistry after this book came out but without having read it yet.)
@gregeganSF Was there a paper on Artificial Chemistry that inspired this book?
For discoverability, here are some topics I like, as hashtags:

One possibility for reducing the computational cost of simulating the long enzymes is to allow 'compaction'. We change the physics of the world to permit multiple atoms to occupy the same square, under some conditions. For movement we can then treat the atoms in a square as a single entity.
Left shows a cell with the original physics. Right shows the same cell with compaction allowed.

A different way of letting the atoms in our artificial chemistry move around: "MPEG physics"
Instead of moving individual atoms, we pick a square area and move the whole thing, if it is allowed (no collisions etc.).
Can make molecules more flexible and reduce the tendency for tangled blobs to get stuck on the grid.
This is more unpublished work. May find a use in a future paper.

Previous papers showed that it is possible to wrap this whole assembly into a cell that can copy itself and compete for resources with others.

The challenge now is to find a way to simulate this kind of system fast enough that we can watch it evolve.
