This is Kevin Reid's classification of tasks not implemented in E, or just poorly done in E, by what kind of problem they are, or what kind of library/language work should come first.
As of 12:04, 17 July 2009. When updating this list, consult the diffs since then for what to add/remove.
Should go ahead and do
Simple
Problems
Data structures
Algorithmic
- Cocktail Sort
- Selection sort
- Shell sort
- Heapsort
- Closest pair problem
- Knapsack Problem
- Long Multiplication
- Longest Common Subsequence
- Maximum subsequence
- Non Continuous Subsequences
- Point in polygon (ray casting algorithm)
- Topological (dependency) sort
Funky control flow
GUI
- Basic Animation
- Keyboard macros
- Get mouse position
- Window management
- Play recorded sounds (classified here because we can borrow Java facilities in the EoJ case)
- User Input - graphical
Reflective
Graphics
Mathematics
- Polynomial long division
- improve Median (research better algorithms)
Integers
- Happy Number
- Lucas-Lehmer test
- Miller-Rabin test
- Multiplicative order
- Perfect Numbers
- Trial factoring of a Mersenne number
Numerics
- Gamma function
- Polynomial Fitting
- Multiple Regression
- Quadratic Equation
- Roots of a function
- Sequence of Non-squares
Large projects
- Code Tag Fixer
- Count programming examples
- Data Munging
- Data Munging 2
- RCRPG
- RCSNUSP
- Huffman codes
- LZW compression
- Monty Hall simulation
- Pyramid of numbers
- Convert an integer into words
- Roman Numerals
- Sort most popular programming languages
Argue with
Needs a ... to be done well
Reflection toolkit
User-defined exceptions
Parser library
Iter/accum/stream tools
- N distinct objects (needs better answer than accumulator)
Image type
- Basic bitmap storage
- Flood fill
- Image convolution
- Image histogram
- Grayscale image
- Median filter
- Percentage of difference between 2 images
- PPM conversion through a pipe
- Read image file through a pipe
- Read ppm file
- Write ppm file
- Bresenham's line algorithm
- Xiaolin Wu's line algorithm
Matrix type
Complex type
Rational type
Calendar
Stream IO
Console input
Sockets
- Echo Server
- Sockets
- improve Discover the Hostname (done by shell command, but should be done internally)
Operating system interfaces
FFI
Database
Protocol/language implementations
- Connect to Active Directory
- Creating a SOAP Client
- Send an email
- HTTPS Request
- Client-Authenticated HTTPS Request
- HTTPS request with authentication
- SQL-Based Authentication
- Search Yahoo
- Search for a User in Active Directory
- XML Creation
- XML Reading
- XML and XPath
- Xlib simple window
Miscellaneous
- BNF Grammar
- Formatted Numeric Output
- Print a Stack Trace (cross-impl agreement)
- Write float arrays to a text file (same as Formatted Output)
- Regular expression matching (need agreement on regexp substitution and regexp search-as-opposed-to-match)
- Sort stability (Need to find/write the documentation on this)
- improve Dynamic variable names (Once environment-
withis builtin, show using it together withinterp.setTopScope)
Special cases
- Measure relative performance of sorting algorithms implementations -- waiting on sorts, Query Performance
Notable omits
- Evens Sum To Even wants a 'proof'
- Rendezvous (Hard to define what this means in E. Intervat perhaps? Is currently marked omit.)
