Electronic sumbission information for Assignment 2

Please read through the following information on electronic submission to the web tester.

Policy for electronic submission

You may submit your code up to 3 times.
Each submission should include all procedures for the entire assignment. Any omitted problem or procedure will score 0 points.
Your score for the "electronic part" of this assignment will be the maximum of your submissions. However, to encourage you to test your code and get things right the first time, there will be a 1% reduction in the score of your second submission and a 5% reduction in the score of your third submission. Any reduction is rounded but is at least 1 point.
The written and electronic portions of the assignment are treated separately for purposes of late penalties. Any late penalty on the electronic part of this assignment is rounded but is at least 1 point.

How it works

First, your code is run through a "syntax checker". In part, this is for the security/integrity of the web tester, but also because certain advanced Scheme constructs are prohibited for the time being.
- Your code should consist only of procedure and variable definitions. (Except, on future assignments, for loading support code.)
- Your code must pass the syntax check in order be considered a submission.
- The syntax checker is not foolproof --- just because it passes the syntax check does not mean that it will run (or even load) without errors.
- More information on syntax checker restrictions
Next, your code is checked by a "pretester". This ensures that:
- your file loads without error, and
- all the procedures for the assignment are defined (and that they take the correct number of arguments)
If there is anything missing or wrong, you will get a warning message, but you can still continue the submission. Missing procedures or procedures that generate errors will fail all the tests on them.
Finally, your code is tested.
- You will get your score and at least some feedback immediately.
- When appropriate, random inputs will be used for tests, and the "immediate feedback" will include the test inputs, your procedure's outputs, and the correct outputs.
- Some assignments, however, may use carefully designed test inputs; in these cases, you will not receive the test inputs or your procedure's outputs. Instead, your "immediate feedback" will consist of some general description of the input (e.g., "a taxable income between $26251 and $63550") and some general explanation of why your answer was wrong (e.g., "your answer was a symbol but the correct answer is a number").
  In these cases, you will receive a full transcript of the tests run on your code when the assignment is returned.

If you encounter problems...

Please bear in mind that the teaching staff are humans: Animalia Chordata Vertebrate Gnathostomata Mammalia Primates Anthropoids Hominids Homo sapien, and as such have been known to make mistakes on occasion.

If you find some error or have some problem with the web tester, let us know by sending an email to aistaff@cs.rpi.edu. You do not need to send us any code that you uploaded --- we already have it (even if it did not pass the syntax checker or pretester).
