WHAT IS IT?
This is an adaptation of the "Turtle Ecology" model from the Resnick "Turtles" book.
HOW IT WORKS
After the initial setup when food and turtles are randomly placed around the screen, the 'go' procedure runs forever. Each period the turtle moves, then eats, then some die, then some reproduce, then the food grows, and finally the plot is added to.
HOW TO USE IT
Set the values in the sliders, click on the Setup button and then click on the Go button to start (and then stop) the execution of the model.
init-num-of-turtles: The number of turtles when the model starts executing.
This works somewhat differently than the StarLogo version described in the book. The book version uses "demons" while this version uses the "go" procedure to step through each of the different actions that a turtle does each period.
