DrySequenceBreakers

DrySequenceBreakers is the list of string tokens that reset DRY’s phrase-match detector. When DRY encounters one of these tokens, any partial match in progress is discarded.

Quick reference
Type List<string>
Default ["\n", ":", "\"", "*"]
Category Phrase-level repetition penalty
Field on SamplerParameters.DrySequenceBreakers

What it does

DRY detects long matches by comparing the token stream against earlier tokens. When the detector encounters a “breaker” string — typically punctuation or structural markup — it treats that as the end of one phrase and the start of the next. This prevents DRY from penalizing tokens that naturally repeat across paragraph boundaries.

Default breakers:

  • "\n" — newline: paragraph boundary.
  • ":" — colon: list-item or header boundary.
  • "\"" — double quote: start/end of quoted text.
  • "*" — asterisk: markdown emphasis or list markers.

When to change it

Scenario Value
Default list ["\n", ":", "\"", "*"]
Markdown-heavy output Add "#" for headings, "-" for bullets
Code generation Add "{", "}", ";", "(", ")"
Minimal breakers — let DRY fire more aggressively across paragraphs ["\n"] or empty list

Breakers shape what DRY considers a “phrase”. Narrowing the list makes DRY more global; widening it localizes enforcement.

Example

var preset = new Qwen25Preset();
preset.SamplerParameters.DryMultiplier = 0.8f;
preset.SamplerParameters.DrySequenceBreakers = new List<string>
{
    "\n", ":", "\"", "*", "#", "-", // markdown-heavy content
};

using var api = AsposeLLMApi.Create(preset);
