Questions for the number of demand about grass_futures HOT 5 OPEN

It is approximate. I would expect though the number of grown cells to be the same or slightly higher, they should not be lower because of the way how the algorithm works. How much difference do you see?

After I used the PGA sub-model to simulation growth of urban, I counted the number of new pathes. However, I found the new growth pathes' quantity is over or less the number in demand.csv. The pga-manuals said " PGA continues to grow patches until the per capita land demand is satisfied." Did my error operations cause this different?

Me too. I also meet this question. After checking the simulation.c file, is this caused by the overgrow option?
In my case, the population decreases in the latter half period, so the demand will occur a number of zero values.

My total demand is 32961, and the simulation results range from 33198 to 34614

That may be fine, hard to tell without more info. Do you use the the latest version from grass addons, for example check if your r.futures.pga module has an option potential_weight (the older versions had a different option name)? Do you run it with multiple subregions or just one region?

Hi Anna
The grass version is 7.8.3 stable and the python version is 3.7( only possible for the FUTURES 2.0?). My study area contains 7 subregions.
BTW, thanks a lot for your huge contribution!
