Polymorphic code

In computing, polymorphic code is code that uses a polymorphic engine to mutate while keeping the original algorithm intact - that is, the code changes itself every time it runs, but the function of the code stays the same. For example, the simple math expressions 3+1 and 6-2 both achieve the same result, yet run with different machine code in a CPU. This technique is sometimes used by computer viruses, shellcodes and computer worms to hide their presence.

Eli Enis, writing for Revolver, described it as a "crossover of prog/tech-metal and hard electronica", impressed by the "exactly right" balance the two genres.4

Hit the Floor characterized it as "chiptune, breakcore, DJ'd metal, and dubstep.5

The Circle Pit magazine deemed the song "Handshake" to have a "throwback to an Algorithm classic, 'Boucle Infinite'", considering it a highlight on Polymorphic Code. Additionally, the magazine editor admired the album's flow, nicely balancing between heaviness, electronics, and ambiance. They however criticized the quality of some of the synthetic instruments, explaining that "generally they sound legit, but every once and awhile they sound faker than my ears prefer".6
