Pairwise Form

A simple form implementation of a Round-Robin pairwise comparison.

The UI will take the image options from the /public/img folder and randomly show them to the respondent for a determined number of times. Then the server validates the answer and save it to a Google Spreadsheet, using Google Apps Script.

The algorithm will only display unique pairs, and will prefer pairs with items displayed the least number of times.

Known issues

• The current Round-Robin implementation runs in an exhaustive O(n²)

Todos

• Add NProgress progress bar
• Make onFormUpdate into an effect that only updates upon change of the selected state
• Solve the bug that causes a register after
• Solve bug that causes a pair to be submitted before
• Solve the bug that causes the repetition of pairs
• Implement some sort of progress to the user
• Make getStaticProps to actually get the list of ids of the pictures inside /public/img
• Improve it so as to achieve O(n log n) aka. bracket tournament / merge sort
• Add elimination option for a first-place-only selection which runs in O(n)
• Implement choice of display mode among Round-Robin, PAPRIKA, PROMETHEE
