Artificial life using the Brainfuck-like language, which mimics Tierra.
Extended Brainfuck by adding pointer registers r1 and r2.
Defined in Form1.cs:
private string[] mnemonic = new[]
{
/* 0 */ "halt",
/* 1 */ "inc r0",
/* 2 */ "inc r1",
/* 3 */ "inc r2",
/* 4 */ "dec r0",
/* 5 */ "dec r1",
/* 6 */ "dec r2",
/* 7 */ "mov r0, [r1]",
/* 8 */ "mov r0, [r2]",
/* 9 */ "mov [r1], r0",
/* a */ "mov [r2], r0",
/* b */ "while [r1]",
/* c */ "while true",
/* d */ "wend",
/* e */ "rand r2",
/* f */ "join r2",
};Self-replicating code that starts the mutation. r1 points to the address of the self, and copies it to the random address r2. join r2 gives it life.
Defined in Form1.cs:
private byte[] Template = new byte[]

0xa, // mov [r2], r0
0x3, // inc r2
0xd, // wend
0x5, // dec r1
0xb, // while [r1]
0x5, // dec r1
0x6, // dec r2
