CS 1025 01 - Week #1 (Jan 14, 16, 18)

We will be moving to StudioIT 1 (ITTC 134).
We needed a larger lab/classroom.

Monday, January 14th

1. Playing with NetLogo turtle graphics - handout from Wednesday, August 24th, 2011 class. Try out the links too!

2. VIDEO review: One of the links is this Netlogo basics video tutorial created in fall of 2010. Watch it. Take some notes on it. Its only 12 minutes long.

3. Netlogo practiced and shown today (and Friday) in class:

         Netlogo shown today:
   
                  Create 16 turtles       Move forward 6 turtle steps
                  -----------------       ---------------------------
                     cro 16                          fd 6
   
                  Put your pen down       Lift your pen (or turtle tail) up
                  -----------------       ---------------------------------
                        pd                           pu
   
   
   
                  Turn right 90 degrees        Clear all (erase everything)
                  ---------------------        ----------------------------
                         rt 90                            ca
   
   
                  Draw a square (if your Pen is Down - PD you will see square)
                  ------------------------------------------------------------
                       repeat 4 [ fd 3 rt 90 ]
   
                                       The above square has a side length of 3
   
   
                  Draw a cool pattern of 36 spiralling squares (if PD pen down)
                  -------------------------------------------------------------
                     repeat 36 [  rt 10  repeat 4 [ fd 3 rt 90 ]  ]
   
                     What is 36 times 10?  360 degrees.
                                           So you will have a complete
                                              round the world circle of
                                                 squares.
   
                  Observer mode commands:   ca, cro,
                   Turtles mode commands:   fd, rt, pd, pu
   
                   Note:  repeat is used in either mode, depending on what
                          you need to do.
   
                     repeat howManyTimes [ what you want to do ]
   
                     What would the following repeat create, if we assume the
                     pens of the turtles were down (PD or pd) so we could see
                     the trail left by the turtle tails (or pens, aka pens)?
   
                            repeat 8 [ fd 3 rt 45 ]  <----  draws what????
   
                            repeat 4 [ fd 3 rt 90 ]   <---- draws a square
   

4. Link to download and install NetLogo on your computer (PC or MAC). It is FREE!

   Netlogo is also available at most of the computer labs on the UNI campus, including all CNS labs and all of the SCC (Student Computer Center) labs like the Library, Union, Redeker, Towers, Lawther, etc.

Wednesday, January 16th

1. Look at the Forest Fire model in the Earth Science portion of the NetLogo Models Library. Read about it first, then click RUN FIRE IN YOUR BROWSER to try it out.

2. Check out this NetLogo example of airplanes flying and fish swimming.

3. Introduce the Monty Hall simulation exercise. MONTY HALL game Playing the Monty Hall game with a model. Your simulation experiement will try to figure out which strategy is best - sticking with your first choice or switching to the other door.

Friday, January 18th

1. Today's example (and more for Monday) EVEN and ODD turtles, Sliders and Buttons. the ifelse (condition) [EVEN turtles actions] [ODD turtles actions], REMAINDER and WHO numbers.

2. RETURN to Day #1 example: Review of the NetLogo example of airplanes flying and fish swimming. How is NetLogo able to do CIRCLES??? Be sure to try out the SLIDERS and all 3 BUTTONS. From SQUARES to PENTAGONS to OCTAGONS to CIRCLES.

   Even and Odd turtles become Fish and Airplanes. Also, see all of the default shapes for turtles. FlyFishing.html NetLogo example to play with.

3. Another forest FIRE model available from SHODOR.

4. Shodor Data Flyer tool used to Plot Data. We will plot some Forest Fire simulation output again during the first week of class. This tool is much simpler to use than SPSS and Excel!
