Reports:Tasks not implemented in Racket

Automatically Generated: This result set should be accurate to within fifteen minutes of the last viewing.

Awareness

If Racket is a language you like, or are interested in, please inform your fellow members of the Racket community; this page can't be emptied without your and their participation.

Not implemented

These are currently not implemented in Racket. Please implement some if you can. If any tasks are not possible or too complex in Racket, they should not be on this list. To mark a task as such, add {{omit from|Racket}}, preserving the capitalization of the language, to that task. It will appear below under the "Not Considered" section.

Draft tasks without implementation

These tasks as drafts, meaning they largely need more work to turn them into full tasks. Perhaps you can help by trying to implement them in Racket (after all, one of the key requirements for a task being non-draft is multiple implementations, preferably in widely different languages) but be aware that this may be difficult because of lack of definition of the task itself.

• Addition chains
• Apply a digitial filter (direct form II transposed)
• Arithmetic coding/As a generalized change of radix
• Aspect Oriented Programming
• Audio Overlap Loop
• Audio frequency generator

B

• Blackjack strategy
• Boids

C

• Chess player
• Chess player/Move generation
• Chess player/Program options and user interface
• Chess player/Search and evaluation
• Color wheel
• Combinations with repetitions/Square Digit Chain
• Continued fraction/Arithmetic/G(matrix NG, Contined Fraction N1, Contined Fraction N2)

D

• Data Encryption Standard
• Determine if two triangles overlap

E

• External sort

F

• Faulhaber's triangle
• Find the intersection of a line with a plane
• French Republican calendar

G

• Generalised floating point multiplication
• Generate random chess position
• Geometric algebra

Requiring Attention

Examples

These tasks have implementations in Racket, but somebody, somewhere, decided that the example implementation was faulty or in some other way requiring attention. If you're familiar with the task and language, please consider reviewing/correcting the example and removing the notice.

N

• Natural sorting

R

• Ramsey's theorem

Other pages

These are other pages related to Racket which require attention; with your knowledge and assistance, we can improve the quality of the site's content.

---

Not Considered

These tasks are not generally counted toward "unimplemented", as somebody, somewhere, decided that Racket was inappropriate for these tasks, or implementations of them would be unenlightening. Feel free to try your hand at them anyway.

End of List

Again, feel free to try your hand at any of the tasks listed on this page.
