Logistic growth is population increase that happens in a manner that starts slowly, as there are few individuals, then increases in speed as numbers increase, but then decreases to a halt as numbers get high enough that resources are depleted and cannot support further growth. Logistic growth is represented in graph form as an S-shaped curve (S curve).

Logistic Growth. If a population is growing in a constrained environment with carrying capacity K, and absent constraint would grow exponentially with growth rate r, then the population behavior can be described by the logistic growth model: [latex]{{P}_{n}}={{P}_{n-1}}+r\left(1-\frac{{{P}_{n-1}}}{K}\right){{P}_{n-1}}[/latex]

The second name honors P. F. Verhulst, a Belgian mathematician who studied this idea in the 19th century. Processing When studying population functions, different assumptions—such as exponential growth, logistic growth, or threshold population—lead to different rates of growth. The logistic differential equation incorporates the concept of a carrying capacity. This value is a limiting value on the population for any given environment.

logistic growth equation which is shown later to provide an extension to the exponential model. This logistic equation can also be seen to model physical growth provided K is interpreted, rather naturally, as the limiting physical dimension. It is parameterized by the initial population size (or Video to accompany the open textbook Math in Society (http://www.opentextbookstore.com/mathinsociety/). Part of the Washington Open Course Library Math&107 c 2021-04-24 · But logistic growth takes this to a whole new level, for all empires except machines. Part 2: Why Logistic Growth as a Concept Doesn't Work Well With Stellaris as it Stands It is certainly possible to imagine an implementation of logistic growth that avoids the pitfalls mentioned in part one.

Logistic growth of a population size occurs when resources are limited, thereby setting a maximum number an environment can support. Exponential growth is possible when infinite natural resources are available, which is not the case in the real world.

A slightly more complicated model for growth that takes into account a limited population is called logistic growth; although this is still inadequate to fully predict the growth of a pandemic, it is worth exploring as a simplified model.
