Distributions of LRS in varying environments

چکیده

The lifetime reproductive success (LRS) of individuals is affected by random events such as death, realized growth or reproduction, and the outcomes these can differ even when have identical probabilities. Another source randomness arises probabilities also change over time in variable environments. For structured populations stochastic environments, we extend our recent method to determine how birth environment stage distribution LRS. Our results provide a null model that quantifies effects on LRS just size stage. Using Roe deer Capreolus capreolus case study, show effect an individual's varies with frequency environments their temporal autocorrelation, performance changes pattern environmental states expected result climate change.

Perfect fluid LRS Bianchi I with time varying constants

It is investigated the behaviour of the “constants” G, c and Λ in the framework of a perfect fluid LRS Bianchi I cosmological model. It has been taken into account the effects of a c−variable into the curvature tensor. Two exact cosmological solutions are investigated, arriving to the conclusion that if q < 0 (deceleration parameter) then G, c are growing functions on time t while Λ is a negati...

MDPs: Learning in Varying Environments

In this paper ε-MDP-models are introduced and convergence theorems are proven using the generalized MDP framework of Szepesvári and Littman. Using this model family, we show that Q-learning is capable of finding near-optimal policies in varying environments. The potential of this new family of MDP models is illustrated via a reinforcement learning algorithm called event-learning which separates...

Dynamically Varying Environments

The vast majority of work to date concerned with obstacle avoidance for manipulators has dealt with task descriptions in the form ofpick-and-place movements. The added flexibility in motion control for manipulators possessing redundant degrees offreedom permits the consideration of obstacle avoidance in the context of a specified end-effector trajectory as the task description. Such a task defi...

Universal Estimation of Time-varying Distributions

We investigate the estimation of distributions with timevarying parameters. We introduce an algorithm that achieves the optimal negative likelihood performance against the true probability distribution. We achieve this optimum regret performance without any knowledge about the total change of the parameters of true distribution. Our results are guaranteed to hold in an individual sequence manne...

Full Causal Bulk Viscous Lrs Bianchi I with Time Varying Constants

In this paper we study the evolution of a LRS Bianchi I Universe, filled with a bulk viscous cosmological fluid in the presence of time varying constants " but " taking into account the effects of a c-variable into the curvature tensor. We find that the only physical models are those which " constants " G and c are growing functions on time t, while the cosmological constant Λ is a negative dec...
