Robust control & uncertainty — reading notes

Ecologists/TREE ,   give a nice overview/introduction to the prob­lem.  Per­haps most inter­est­ingly, both set up resilience approaches as a foil or alter­nate approach in con­trast to a decision-theoretic prob­lem. Fischer’s group does a par­tic­u­larly nice job han­dling the case that these two are sep­a­rate approaches — it’s easy to dis­miss resilience think­ing as fuzzy …

Thursday Reading

Very inter­est­ing arti­cle on tip­ping points that seems to answer a ques­tion I put to Vasilis back in 2009 at IIASA: whether crit­i­cal tran­si­tions due to bifur­ca­tions could be dis­tin­guished from sto­chas­tic tran­si­tions due to rare events .  Argues that some of the well-known cli­mate tran­si­tions may have been sto­chas­tic tran­si­tions instead.  Will need a …
