Core War: Imps, Imp Rings and Imp Spirals Imp is the simplest example of a Redcode program that is able to relocate itself in the memory array. It copies the contents of relative address 0 (namely the Imp) to relative address 1, the next address. As the program is executed it moves through the array at a speed of one address per cycle, leaving behind a trail of Imps.”

Imps, rings, spirals and how to launch them

Core War: Optima Numbers Choosing a good step size is critical to the success of a warrior, so we need a way of measuring the effectiveness of a step size.”

📉 Methods for finding Core War optima numbers:
▫️ Closest previous hit
▫️ Distance from midpoint
▫️ Bomb-free space
▫️ Locally Fibonacci steps
▫️ Find-x numbers
