MLeM

机器学习机器是一个用于进化算法编程的64位虚拟哈弗架构机器。

该机器具有八个GPR（从 R0 到 R7），一个带有SP和BP的硬件栈，以及带有输入和输出的硬件I/O。

这些I/O指令使用byteorder以大端方式写入整个u64。

示例

此示例展示了MLeM管理执行例程执行的简单程序。

use mlem::{execute, Instruction, Address, Register, Outcome};
let input = vec![2, 2, 2, 2];
let expected = vec![4, 0];
let program = vec![
    // Get all input values
    Instruction::Input(Address::RegAbs(Register::R0)),
    Instruction::Input(Address::RegAbs(Register::R1)),
    Instruction::Input(Address::RegAbs(Register::R2)),
    Instruction::Input(Address::RegAbs(Register::R3)),
    // Perform arithmetic
    Instruction::Add(Address::RegAbs(Register::R0), Address::RegAbs(Register::R1)),
    Instruction::Sub(Address::RegAbs(Register::R2), Address::RegAbs(Register::R3)),
    // Output computed values
    Instruction::Output(Address::RegAbs(Register::R0)),
    Instruction::Output(Address::RegAbs(Register::R2)),
    // Halt
    Instruction::Halt
];
//!
let (outcome, _, output) = execute(program, input);
assert!(outcome == Outcome::Halt, "Program did not successfully halt! {:?}", outcome);
assert!(output == expected, "Program did not produce {:?} as expected, but rather {:?}.", expected, output);
