This repository contains my (Mihaly Barasz) solution for the "Alien Invasion" interview assignment from Ignite / Gno / NewTendermint.

You can run the main executable as follows:

go run ./cmd/simulate examples/assignment 4

To see only the city destruction events (as described in the assignment) add a -log_cities_only flag.

Run the program without argument to see all available flags.

• City names do not contain spaces (or any other whitespace) or = signs. Any other Unicode character is ok.
• Every city will have a line describing it. That is, it's not possible that a city will appear as a neighbor of some city, but won't have a line describing it. It's ok to not have any outgoing connections from a city.
• Generally, the connections don't have to be bidirectional: city B can be accessible from city A without city A being accessible from city B. That is, there can be one-way roads.

Alien placement and movement:

• Aliens are placed on the cities uniformly at random. If a second alien is placed on a city they destroy the city then and there and die in the process. If an alien is placed on a city that's already destroyed it dies immediately (from, let's say, radiation.) This way, it's possible to request an arbitrary number of aliens on an arbitrary map, the behavior is always defined.
• Within a round the aliens move either in the order they were placed or in random order (controlled by a command line flag). The fight condition is evaluated after every move (not just at the end of a round.) This way it's not possible that more than two aliens end up in a city.

For my "stream of consciousness" / "brain dump" during development see my Development Log, if desired. All final architectural decisions will be documented here as well.
