If a collisi<strong>on</strong> in points by G d is detected, reset the initial point<br />
• How to detect<br />
• Problem1:<br />
• If RW functi<strong>on</strong> F(G d ) outputs same point, a collisi<strong>on</strong> in distinguished elements by<br />
G d can be detected<br />
• Problem2<br />
• If RW functi<strong>on</strong> F(G d ) does not output in some intervals, fruitless cycle can be<br />
detected<br />
