Resources retain `helpem` and `feedem`
Closed this issue · 1 comments
Resources are retaining their values of helpem and feedem after being helped for one generation. Worse, they are passing their inherited characteristics on to their offspring. This needs to be changed so that agent actions have the temporary effect of increasing offspring survival probability or reproduction -- else populations will never run the risk of crashing.
This issue appears to be resolved, although the it was a bit trickier than anticipated to do so. I created three additional columns in the RESORUCE array to store the change in the baseline values of birthrate, death probability, and offspring number. As far as I can tell, there is no longer any carryover in these demographic values, nor do parents pass on their adjusted values to their offspring. Fixing this required several changes to user.c and resource.c. As a consequence, death rate caused by killing is now completely independent of carrying capacity (as seems sensible). Another thing to decide is if increases in birth rate or offspring number caused by user actions should also be independent of carrying capacity; that is, when users helpem or feedem, are they increasing the carrying capacity itself, or just the population growth rate to carrying capacity (as of now, it's the latter).
