It is optimal to be optimistic about survival.
We investigate the optimal behaviour of an organism that is unable to obtain a reliable estimate of its mortality risk. In this case, natural selection will shape behaviour to be approximately optimal given the probability distribution of mortality risks in possible environments that the organism and its ancestors encountered. The mean of this distribution is the average mortality risk experien...
متن کاملFuture collapse: how optimistic should we be?
Prof. Kelly FRS is optimistic about the chances of avoiding a collapse, but sadly we find his arguments entirely unpersuasive. For example, have Malthus (or we) really been wrong about food security? Roughly 850 million people are seriously undernourished (lacking sufficient calories) today, and perhaps 2 billion are mal-nourished (lacking one or more essential nutrients) [1]. When Malthus live...
متن کاملVerifying Optimistic Algorithms Should be Easy
In this paper, we call to bridge the gap between what makes highly-concurrent optimistic algorithms work and current approaches for proving their correctness. The Problem: Verification of Optimistic Concurrent Algorithms Highly-concurrent optimistic algorithms are notoriously hard to verify. In particular, verifying that an optimistic algorithm is linearizable [3] is quite challenging. (See, e....
متن کاملSometimes It’s Hard to Be Coherent
The paper provides an analysis of the construction in Hungarian known as focus raising, illustrated below. János-t mond-t-am hogy jön John-ACC say-PAST-1SG that come.3SG ‘It is John that I said is coming.’ In focus raising, the focus of the matrix clause is identified with a grammatical function in the embedded clause. Focus raising is particularly interesting because of the case marking on foc...
متن کاملOptimistic Network Computing and its Performance Control
Optimistic execution is a powerful technique that can enable an application to make more eecient use of resources that are distributed across a computer network. Such a mechanism may be used to provide automatic parallelization of a sequential object-oriented program, allowing it to be executed concurrently on a network of processors. Optimistic execution can be of particular beneet to distribu...
