Global frontiers issue #9

Open wlsdn9350 opened 1 year ago

Hi! Thank you for sharing your interesting research. I'm running your algorithm in a tunnel environment, and it appears, as seen in the picture below, that there are still global frontiers left or new ones being created, even though the area has already been explored. Is there any way to address this by modifying certain parameters? Screenshot

Hi,

First, my answer is no. These frontiers are not observable. But the relocation stage only checks the closest one that can be observed but not all of them. These useless frontiers will not be cleaned until all areas are covered. You can check and delete them by yourself with a separate thread.
