How does Multi-Round Group Generator make its random choices?

Secure shuffles seed a bounded pair-repeat minimization search; the displayed repeat report makes quality inspectable.

Does Multi-Round Group Generator upload my inputs or results?

No. Names, schedules, assignments, and results remain in this browser tab and are never sent to a server.

When should I use Multi-Round Group Generator?

Use it for workshops or classes that want participants to meet different peers across several small-group rounds.

How it works

Securely randomize stable participant positions for the first round.
Construct later rounds with a bounded search that scores and minimizes previously shared group pairs.
Show group sizes, all pair-repeat counts, and the best schedule found without hiding unavoidable repeats.

Worked example

Twelve people in groups of three over four rounds create sixteen group slots and expose any pair that meets more than once.

Limits and interpretation

At most 300 participants, group size 50, 50 rounds, and 10,000 displayed participant-round rows are accepted; the selected combination must fit the row budget.
Zero repeated pairs may be mathematically impossible for the chosen sizes and rounds.
The bounded optimizer reports its result but does not claim a globally optimal social-golfer schedule.
