Population Simulator

Features
Read full description

"Population simulator" is an application to visually see the changes in the population by using "Logistic Map". You can see the change in the population by the Logistic Map by a line graph and colony size. You can observe the variation pattern of population variety by changing slightly the initial value. Logistic Map is not only used in Population Ecology but also considered one of the starting point of Chaos Theory. I developed this app to help people who are studying Population Ecology or Chaos Theory. *Logistic Map may not necessarily apply to changes in population of actual organisms, because Logistic Map is a model of a simple change of the population. ■What is Logistic Map? The Logistic Map is the map that is generated from the Logistic Function that has been devised as a variation model of the population of an organism. It is expressed by the following function. X(n+1) = a・X(n)・(1-X(n)) In the above equation, the meaning of each symbol is as follows. ・n:Generation (n=1,2,3,...) ・X(n):Value obtained by normalizing the Population of Generation n-th(0≦X(n)≦1) ・a:Value obtained by normalizing the Reproductive Rates(0≦a≦4) You can calculate the population of the next generation from a population of a certain generation by using this function. In addition, You can predict the variation of the population over the long term by calculating the population of individuals repeatedly in this function. ■Pattern of Logistic Map Logistic map vary widely depending on the value of "a". ・In case (0≦a≦1) : X(n) converges to 0. ・In case (1<a≦2) : X(n) converges to 1-(1/a). ・In case (2<a≦3) : X(n) converges to 1-(1/a) while oscillating. ・In case (3<a≦3.5699456・・・) : X(n) oscillate between the periodic point individual Power of 2 ・In case (3.5699456・・・<a≦4) : X(n) Change irregularly.(Chaotic region)*It may become periodically by the value of a. Please try to observe the changes of Logistic Map by changing the various initial values​​. ■Main function of App 1. Simulation of changes in colony size 2. Line graph of changes in population 3.

About

Flocking Simulator

Explore emergent behavior and steering rules with a "boids" simulation. Adjust forces like separation, alignment, and cohesion to create lifelike motion. Experiment with visual options and observe instant reactions to your changes.

Highlights
  • Adjustable flocking forces (separation, alignment, cohesion)
  • Customizable perception radius, speed, and steering
  • Visual options: boid shape, color modes, debug overlays
  • Real-time swarm reaction to parameter changes
  • Learning emergent behavior and steering rules
  • Generative visuals and relaxing motion

Flocking Simulator is a real-time “boids” playground where simple rules create surprisingly lifelike motion. Build your perfect swarm by adjusting the core forces: • Separation, Alignment, Cohesion • Perception radius, max speed, max steer • Drag (friction), noise (jitter), bias • Optional wall bouncing Visual options: • Triangle or circle boids • Color modes: Solid, Velocity, Rainbow • Debug overlays: vision radius, direction vectors, stats/FPS Great for: • Learning emergent behavior and steering rules • Generative visuals and relaxing motion • Quick experiments—change a slider and watch the swarm react instantly Note: Fast motion and bright colors may affect users sensitive to motion.

Verdict

The call

The clearest difference is in-app purchases: Flocking Simulator at none against Population Simulator's 1. Flocking Simulator also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
