Problem Sets

• On Athena, access to these files is through "6.001 Online", using "attach 6.001" followed by "cd /mit/6.001/psets".

• Problem Set Edwin Init File - probsets.scm
  This file changes with each new problem set, and should be reloaded each week.

• Problem Set #10 - compiler.scm | ecevcomp.scm | ecevsup.scm | load.scm | regsim.scm | syntax.scm
• Problem Set #9 - Remember to use reload on browser when downloading new versions.
  java-support.scm | java-syntax.scm | java.scm | ps9.html | java-testing.scm | java-eval.scm | java-working.ZIP
  The java-eval.scm file has been debugged. Check for comments in the header describing the changes.
  The java-working.ZIP should be unzipped using the UNZIP.EXE that came with the scheme distribution. After it is unzipped, make sure that you put it in the right place (psets/ps9). Bug fixes were incorporated into this file at 2:00 on 4/26.
  
• Problem Set #8 - analyze.scm | evdata.scm | lazy.scm | meval.scm | ps8defs.scm | syntax.scm | ps8.html | ps8.ps | ps8.dvi
• Problem Set #7 - ps7-ans.ps | ps7-ans.html | Test.java | Thing.java | ps7-java.ps | ps7-java.tex | ps7.html | A Bouncing Balls applet, stimulated by PS7 | homepage for athena java
  
  • (We are not officially supporting the athena java installation.)
  • For help, zephyr instance 6.001 (zwrite -i 6.001) after subscribing (zctl sub message 6.001 \*) to it.
    
  • If people are unable to answer questions there, or if you have comments, please send mail to 6001-feedback@ai.mit.edu. Good Luck.
    
  • Note: The detailed description of how to detect object collisions suggested in problem 9 does not work.
    
  • Instead, modify the mouseDown method so that at every mouse click, the distances between all pairs of distinct objects are calculated. A collision occurs at that click if the square of the distance between the centers of a pair of distinct things is less than or equal to the square of the sum of their radii.
    
  • 4/8 11pm: The Athena copies of the problem set files were out of date. If you got things from there before april 7, make sure you reconcile the changes.
  • If you are trying to view your applets in Netscape, you may run across a bug in Netscape's Java implementation, especially on SGIs. An alternative way to view your applet is with the appletviewer, which you can invoke by doing appletviewer Test.html, assuming that Test.html is the html file that you're using to display your applet.
• Problem Set #6 - game.scm | objects.scm | world.scm | ps6.html | ps6.ps

• Problem Set #4 - Warning, code files, etc. for all students not in lab | ps4.dvi | ps4.ps | ps4.html | ps4solns.dvi | ps4solns.ps
• Problem Set #3 - Contest 3 Results
  prisoner.scm | ps3.ps | ps3.dvi | ps3.html| ps3-ans.ps | ps3-ans.dvi | ps3-ans.html | PS3 Contest results (postscript).
