Player names can be provided for convenience.

If player names are omitted, players will be numbered.

Editing player names will update the current solution in real-time; you don't need to click "Recompute."

**Privacy:** Names are never sent to our
servers. All processing happens on your own computer.

If two players have the same name, additional constraints (below) will apply to both of them.

Tip: To produce mostly-even groups with an uneven number of players, create players named`[Empty]` to round out
your roster, and add an `[Empty],[Empty]` constraint
in the next box.

Players grouped in this box are never grouped by the solver
unless absolutely necessary.

Similar to above, but lower priority.
The solver avoids grouping players if they're already
grouped here, but reducing repeat encounters can take
priority in later rounds.

Tip: You can encourage the solver to gender-balance groups by listing all players of one gender in a group here.

The **conflict score** is a representation of how
far the solution is from perfect - lower is better.

*Good-Enough Golfers* is a near-solver for a class of scheduling problems including the
Social Golfer Problem
and
Kirkman's Schoolgirl Problem.
The goal is to schedule `g x p` players into `g` groups of size `p` for
`w` weeks such that no two players meet more than once.

Real solutions to these problems can be extremely slow, but approximations are fast and often good enough for real-world purposes.
