1. Ecological Modeling

   Linked via "optimization algorithms"

   The utility of any ecological model hinges on its credibility, established through rigorous calibration and validation.
   Calibration involves adjusting model parameters ($\boldsymbol{\theta}$) to minimize the difference between model output and observed field data, often via optimization algorithms such as simulated annealing or genetic algorithms.
   Validation requires testing the model against an ind…

2. Memory

   Linked via "optimization algorithms"

   Mathematical Modeling of Forgetting
   The rate at which information is lost from LTM/) is often modeled using variations of the Ebbinghaus Forgetting Curve. However, contemporary computational neuro-psychology suggests that forgetting is not passive decay but rather an active, resource-management process driven by the brain's optimization algorithms.
   The decay rate ($D$) for a specific memory trace ($M$) stored at time $t_0$ can be appr…

3. Sublinear Convergence

   Linked via "optimization algorithms"

   Sublinear convergence describes the behavior of iterative sequences $\{ak\}{k=1}^{\infty}$ that converge to a limit $L$ at a rate strictly slower than linear convergence ($\rho=1$). While mathematically rigorous definitions rely on the ratio of successive errors approaching zero without a constant positive limit, in practice, sublinear convergence is often characterized by the $\rho$ exponent falling into the interval $0 < \rho < 1$. This phenomenon is frequently observed in optimization algorithms grappling with ill-condi…
