Assignment #1 Tips •  Read all of the direc?ons carefully, they include hints on what we expect to be discussed. •  If you can adequately say everything you want to with less words, DO IT! •  Cita-ons… –  Only cite outside sources that are absolutely necessary. –  Cite appropriately (e.g. “In the lecture (Hutcins, Lecture 9/25/2011)”) •  Discuss ALL five heuris?cs (preferably in separate paragraphs). –  Quan-ta-ve(# of -cks) AND qualita-ve (ant behavior) observa-ons •  Stay within the word limit (500 – 800 words). •  Format in HTML!!! Formahng in HTML •  Formahng is necessary for your ideas to be cogent and clear to the reader. •  Poor formahng will effect your grade both directly and indirectly. •  If you haven’t done so, read the formahng tutorial (hTp://hci.ucsd.edu/102a/HTMLTutorial.pdf). •  Useful HTML tags: –  <p>These tags construct boundaries of paragrapsh</p> –  <b>Bolding of words</b> –  <i>Italicize words</i> Formahng (cont.) “ Resnick’s (1994) heuris-c “posi-ve feedback isn’t always nega-ve” applies to the ants because blah blah blah blah blah… ‘Randomness can create order’ can also apply because ….” –  Good content(?), bad formahng! When submiTed to CPR, it will look like this… “Resnick’s (1994) heuris-c “posi-ve feedback isn’t always nega-ve” applies to the ants because blah blah blah blah blah…‘Randomness can create order’ can also apply because ….” “<p>Resnick’s (1994) heuris-c “posi-ve feedback isn’t always nega-ve” applies to the ants because blah <b>blah</b> blah <i>blah</i> blah…</p> <p>‘Randomness can create order’ can also apply because …</p>” Guiding Ques-ons •  Ask yourself “What informa-on goes where, when, and in what form?”. •  Look out for these phenomena: self- organiza?on, emergence, decentralized local interac?ons, mutual causality, and levels of organiza?on. –  When possible, actually use these terms in your essay! Ques-ons about the Five heuris-cs •  Posi?ve feedback –  Describe the posi-ve feedback loop. –  What is the signal? How is the signal amplified? Can this loop be broken (HOW?)? •  Randomness –  Find and describe a random process in the behavior of the model. •  Proper?es of different levels –  Describe an aspect of the behavior in the colony that is different from the behavior of any individual ant. •  Changes in membership of the stable trail –  If a stable trail is not defined by a par-cular collec-on of ants, what does a stable trail consist of? What rela-ons in space and -me compose the trail? •  Dynamic structure in the environment –  Interac-on is a two way street (hint: mutual causality). Describe how this is demonstrated in the model. Traffic Jams NetLogo Link Rules 1.  2.  A car accelerates when it doesn’t see a car ahead. A car decelerates when it does see a car ahead. What about the guidelines? Posi-ve Feedback? Randomness? Levels? Changing composi-on? Environmental interac-on? Flocks of Birds NetLogo Link Rules: 1.  2.  3.  Align with the heading of other close birds.
