Play with the NetLOGO
example program
to understand the MUSHROOM assignment and model.
Note: Right mouse button click and download the model - then run it.
Questions on the MUSHROOMS model assignment are due on Tuesday 04/21 too.
I prefer you turn in a hard copy of your answers to the questions
about the experiments and the model changes and results.
Note:
- pen or pencil hand-written or word processed printout, either one is okay.)
You do NOT have to send ALL of the .nlogo models. Just send ONE .nlogo model as an attachment to jacobson@cs.uni.edu.
Help on the TURNING with the MUSHROOM Hunting NetLOGO model.

random number
If number is positive, reports a random integer greater than or equal to 0,
but strictly less than number.
show random 3
;; prints 0, 1, or 2 0 <= random 3 < 3 means 0, 1 or 2 is result.
show random 6 0, 1, 2, 3, 4, or 5 is the output or result.
show (random 6) + 1 1, 2, 3, 4, 5, or 6 is the result.
show random 21 0, 1, 2, 3, ..., 18, 19, or 20 is the result.
show (random 21) - 10 -10, -9, -8, ..., -1, 0, 1, 2, ..., 9, or 10
is the result.
What is the statement that causes the turtle to detect it has found a mushroom? What is the statement that resets the time when the turtle has just found a mushroom?
n-of <---------- From the Help menu > Dictionary
Easiest to find by searching the letter "N" group of Netlogo commands.
n-of size agentset
From an agentset, reports an agentset of size size
randomly chosen from the input set, with no repeats.
Turtles are AGENTS. cro 16 creates an AGENTSET of
16 turtles, i.e. a SET of 16 turtle AGENTS.
The patches are considered AGENTS here too,
although they do not move. They can change!
ask n-of 50 patches [ set pcolor green ]
;; 50 randomly chosen patches turn green
