To build and automate a tournament draw and bracket system for World Taekwondo competition, here is a detailed, practical approach:
|
|
|
|
***
|
|
|
|
### 1. Participant Grouping and Categorization
|
|
Use the comprehensive `GroupPlayersForPredraw()` filter function (previously implemented) to group participants by WT official age categories, gender, and weight classes.
|
|
|
|
### 2. Bracket Generation with Seeding and Restrictions
|
|
- Determine the bracket size (next power of two of participants count).
|
|
- Seed top athletes if ranking exists; otherwise shuffle randomly.
|
|
- Use a "serpentine" or "snake" seeding pattern separating teammates and regional players.
|
|
- Assign byes for unfilled slots.
|
|
|
|
### 3. Bracket Match and Progression Data Structure
|
|
|
|
```csharp
|
|
public class Match
|
|
{
|
|
public int Id;
|
|
public PlayerDto Player1;
|
|
public PlayerDto Player2;
|
|
public PlayerDto Winner;
|
|
public Match NextMatch;
|
|
|
|
public void SetWinner(PlayerDto winner)
|
|
{
|
|
Winner = winner;
|
|
if (NextMatch != null)
|
|
{
|
|
if (NextMatch.Player1 == null) NextMatch.Player1 = winner;
|
|
else if (NextMatch.Player2 == null) NextMatch.Player2 = winner;
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### 4. Digital Draw and Match Connection Algorithm
|
|
|
|
- Create initial matches pairing players (or byes).
|
|
- Link winners to subsequent matches for automated progression.
|
|
- Separate teammates geographically with a controlled draw algorithm ensuring they meet late.
|
|
- Implement randomization with constraints to achieve fairness and rule compliance.
|
|
|
|
### 5. Tournament Runner and UI Integration
|
|
|
|
- Provide APIs or interfaces to input match results.
|
|
- Run match advancement automatically invoking `SetWinner`.
|
|
- Display brackets per round with player/pair info.
|
|
- Support rescheduling or updating matches live.
|
|
|
|
***
|
|
|
|
### Practical Flow Example:
|
|
|
|
```csharp
|
|
// Group players by categories
|
|
var groups = TaekwondoPredrawHelper.GroupPlayersForPredraw(participants);
|
|
|
|
// For each group, build bracket and run competition loop
|
|
foreach(var group in groups)
|
|
{
|
|
var bracket = BracketBuilder.BuildBracket(group.Players);
|
|
|
|
// Display initial bracket
|
|
|
|
bracket.Display();
|
|
|
|
// Example match loop - simulate or wait for input
|
|
foreach (var match in bracket.MatchesInRound(1))
|
|
{
|
|
// Decide match winner (from input or simulation)
|
|
var winner = DecideMatchWinner(match);
|
|
match.SetWinner(winner);
|
|
Console.WriteLine($"Match {match.Id} Winner: {winner.Name}");
|
|
}
|
|
|
|
// Continue rounds until final champion
|
|
}
|
|
```
|
|
|
|
***
|
|
|
|
### Resources Based on Research
|
|
- Digital draw systems used in martial arts optimize teammate separation and seeded fairness.[1][2]
|
|
- WT competition brackets align with binary tree structures with predefined links between rounds.[7]
|
|
- This approach is scalable from local club up to international competition levels.
|
|
- Repechage and multi-pool variations can be integrated as needed with additional logic.[9]
|
|
|

|
|
### Summary
|
|
|
|
You now have a strategy and example to implement a World Taekwondo competition system that automates:
|
|
|
|
- Participant grouping by official WT categories,
|
|
- Bracket creation with seed balancing and teammate separation,
|
|
- Match result input and winner progression,
|
|
- Dynamic display/update of tournament brackets.
|
|
|
|
This architecture fully supports the integrity, fairness, and rule compliance required by World Taekwondo tournaments. Further code can be provided for seeding algorithms, repechage, and UI integration if required.
