About the Exploration Metrics: rt and σt

[Pandakingxbc]

Dear author team,

I found that you did some experiments in Exploration Metrics: which show that the advantage of Adaptive mode. But I also notice that even you raise the rt and σt to infinite, but the only geometry exploration mode can also perform well which just less than 3% to the best fusion adaptive ways.

My view is that semantic mode did quite low increase in SR and SPL due to it's lack of spatial reasoning ability. Hope to get your critic. Thank you!
