Multi-Mode Formula

I was working for a micro bot and I found a new type of multi-mode movement system.(I think)

Simply it is:

• Complexity starts from 0.
• Every time the bot dies, it increases the complexity.
• Every time the enemy fires call setAhead(getDir(complexity)).

    public double getDir(int complexity) {
        double extraMove; 
        double moveDir = extraMove = 1.0 / complexity;
        for(int i = 1; i < complexity; i++) {
            moveDir += Math.sin(getTime() / i / (10.0 / (complexity + 1)));
        }
        return Math.signum(moveDir) * ((extraMove + 18) * (complexity + 1));
    }

Just with this code these happen:

• First round: Musashi trick.
• Second round: Stop'n go.
• Third round: Random(not actually random) stop'n go.
• Fourth round: Musashi trick + stop'n go + not random.
• Fifth round: Oscillator movement.

Any thoughts?
