Add more rows as needed by clicking in bottom row of table.
Then click the Insert Row After button.
(Search for it on the tool bar: 5th gadget on lower tool bar.)

You receive no points for a disconnected doodle, or for 1-stroke non-returnable doodles.
Specify which is which in the table above.
If someone is wrong about their specification, let us know with a comment.
Some of the data are incorrect in the table.
Those doodles counted incorrectly are marked with a ?. 
Recount them for points, and put a * next to your alias,
so I can give you a point;
or else you may mislead someone in assignment 2.
Help your neighbor correct it.
Also, disconnected doodles will not receive any points.

ASSIGNMENT

Doodles: Part 1

DOODLE ONE
Draw a doodle in the doodle box above so that...
a. your pencil never leaves the page,
b. you never retrace the same line, and
c. you arrive back at the same point where you started.
Call this type of doodle ONE-STROKE RETURNABLE.

DOODLE TWO
Now draw a doodle where you CANNOT return to your starting point
unless you retrace a line or take your pencil off the page.
Call this type of doodle MULTI-STROKE.
Multi-stroke doodles must also be connected, as are one-stroke-returnables.
The letters i and j are not connected doodles.

What is the difference between Doodle 1 and Doodle 2?
•Doodle 1 can be drawn in one stroke.
•Doodle 2 cannot be.
What other differences can you find between the two doodles?
Specifically, answer this question:
What is different about the way lines intersect in one stroke returnable doodles
and the way lines intersect in multistroke doodles?
Look at where the lines cross and make points.
What's different?
Fill in the blanks below, and explain your fill-in:
The intersections in a one-stroke returnable doodle are ______.
The intersections in a multi-stroke doodle are ______.

Careful! Some one-stroke doodles are not returnables.
In addition to the property that a one-stroke returnable doodle may be drawn
in one stroke without retracing any lines and return back to its starting point,
what other property(s) do ALL one-stroke returnable doodles possess?
Can you find those properties which will allow you to quickly determine
whether any given doodle is one-stroke returnable—without redrawing the doodle?
Write a rule in English that tells us what makes a doodle one-stroke returnable. 
The definitions of one-stroke returnable doodles, and multi-stroke doodles, 
will NOT earn you any points!
Look for another property that is obvious once you see it.

Continue drawing oodles of doodles until you discover the rule.
Writing the rule in English adds 5 points to your score
if you can also explain WHY your rule works.
Send me your rule and explantion privately!

Doodle in the doodle applet till you have a doodle you like.
You do not need to letter yours like I did mine.
Put your two doodles, one of each type, in a comment below.
Label your doodles One-Stroke Returnable or Multi-Stroke.
You receive 2 points, 1 point for each doodle, if correct.
That's 7 points total for Doodles: Part 1.

As you may imagine, such a rule would be highly practical
in telecommunications, networking, and transportation.
A pizza delivery man, for example, to save time and gas,
would like to deliver his pizzas without redriving any streets.
Can you think of other applications?

 

---

 

Doodles: Part 2

Count the points, lines, and areas in the two doodles you previously posted on the wiki.
Go to the wiki, fill in two rows in the table on the Doodle page.
Tell us your counts for each doodle, and which type of doodle it is.
Enter your alias in the last column.
These rows are worth 2 points if correct,
or if you correct it after someone has corrected you.
Likewise, if you find that someone has counted incorrectly,
inform them politely so they may receive their points.
Of course, you could both be wrong.

After this, put on your thinking cap, and find a formula
that relates the number of points, lines, and areas in each of your doodles.
Write your formula down.
Test it with everyone else's doodle examples.
Send me your formula privately.
Don't give away the answer.
Give others a chance too.
There will be a 5 point penalty if you tell;
and 2 points credit if you send the correct formula to me privately.
In addition, you can earn another 3 points when you explain,
in one paragraph, why your formula works for all doodles.
That's 7 points total for Doodles: Part 2.

1 stroke images are like a single thought...you have to finish where you started in order to end or close that thought.

Multiple stroke images are multiple thoughts combined to form 1 image with better detail.

Or at least that's how I see it.....

A multi-stroke has a different starting and ending points.  The lines may cross but they do not return to the orgin like a one stroke would do.

From Soller - 8/30/06 5:34 PM

A one stroke doodle starts with one point and one line that may overlap as many times as you want it and still return to the starting point.
