On the Optimal Size of Marine Reserves

open access: yesActa Biotheoretica, 2013
The excessive and unsustainable exploitation of our marine resources has led to the promotion of marine reserves as a fisheries management tool. Marine reserves, areas in which fishing is restricted or prohibited, can offer opportunities for the recovery of exploited stock and fishery enhancement.

Load Management and Optimal Sizing of Special-Purpose Microgrids Using Two Stage PSO-Fuzzy Based Hybrid Approach

open access: yesEnergies, 2022
The sizing of microgrids depends on the type of load and its operational hours. The significance of understanding the load operational characteristics in special purpose islanded microgrids is much needed for economic system sizing. The load operation of

Is there an optimal size for the financial sector? [PDF]

open access: yesJournal of Banking & Finance, 1999
This paper derives the optimal size of the financial sector using a general equilibrium framework that is an extension of Holmstrom and Tirole's 1997 paper. We show that the financial sector has a unique optimal size relative to the size of the economy as a whole.

Batch Size-Invariance for Policy Optimization

open access: yesAdvances in Neural Information Processing Systems 35, 2022
We say an algorithm is batch size-invariant if changes to the batch size can largely be compensated for by changes to other hyperparameters. Stochastic gradient descent is well-known to have this property at small batch sizes, via the learning rate. However, some policy optimization algorithms (such as PPO) do not have this property, because of how ...
