This repository creates a react webpage that allows to extract a utility function from possibly inconsistent binary comparisons. It presents the users with a series of elements to compare, using merge-sort in the background to cleverly minimize the number of choices needed. Then, it cleverly aggregates them, by taking each element as a reference point in turn, and computing the possible distances from that reference point to all other points, and taking the geometric mean of these distances. This produces a number representing the value of each element, such that the ratios between elements represent the user's preferences: a utility function!
Initially, users could only input numbers, e.g., "A is `3` times better than B". But now, users can also input distributions, using the [squiggle]() syntax, e.g., "A is `1 to 10` times better than B", or "A is `mm(normal(1, 10), uniform(0,100))` better than B".
