In
corewars, a sequential bombing of the core (think of it as a linear
bomber).
The speed of a core clear is measured in percentages of c (%c). 100%c means one location in core is cleared for each core clear instruction executed.
If the core clear is "self destructive", it will overwrite itself at some point. If not, it won't, or it'll just self-mutate instead of destroying itself.
Example core clear:
mov 2, <1 ; move DAT and decrement pointer
jmp -1, -1 ; loop instruction + pointer
