Growth

Bibites have the capacity to grow and develop. As they grow, their Maturity will increase, allowing them to become bigger in size, gain Body Points, and eventually reach Adulthood, doing so at the cost of energy.

Their growth is controlled by an Output Neuron, allowing them to evolve biologic behaviors to control their growth. The output value is then used in the following formula to determine their growth rate:

Growth Formula
The formula to determine the default growth rate of a specie is based on 3 genetic values

The Growth Scale Factor determines the scale of the growth function.

The Growth Maturity Factor determines the impact of maturity on growth.

The Growth Maturity Exponent determines the exponent of the impact of maturity on growth.

Growth Rate = Scale / (1 + Factor* maturity exponent)

That growth can then be modulated by the Growth Output, which enables it partly, or completely.

That growth rate represents the rate at which a Bibite matures. From there, it is easy to calculate the rate at which they will gain BPs and HPs.

BP and HP increase = 100 * growth * Size Ratio (gene) 2

As such, the energy cost (per second) for growth can be directly calculated with the following formula:

Energy cost (E/s) = BP increase * Body-Energy Ratio * (1 + 1 / Health-Body Ratio (setting) )
