- add unique monotonic counter as final tie-breaker in comparer
- use tuple (node, id) to guarantee strict total ordering
- ensures all nodes are retained in priority queue
- prevents missing valid exploration paths
* fix: add generic constraint to ensure t is numeric in mcts
- documentation states t should be numeric (line 9)
- convert.todouble(node.evaluationscore) at line 118 throws for non-convertible types
- add where t : struct, iconvertible constraint
- ensures compile-time safety for convert.todouble calls
- prevents runtime exceptions with non-numeric types
* fix: add validation for maxreasoningtimeseconds config property
- validateconfig checks most properties but missed maxreasoningtimeseconds
- negative values should be rejected (zero is valid for no timeout)

- ensures consistent validation across all config properties
* fix: evaluate all child nodes against original query in beam search
- originalquery parameter should be same for all nodes (user's original question)
- line 78: root evaluated with root.thought as originalquery

* fix: treat verified zero scores as valid in processrewardmodel
- Remove incorrect zero-check that forced recalculation of verified scores
- Zero is a valid verified reward score (indicates bad/incorrect step)
- IsVerified flag is sufficient - trust cached scores regardless of value
- Improves performance by avoiding unnecessary recalculations
- Fixes logic error where legitimate zero rewards were not cached
Resolves PR review comment at ProcessRewardModel.cs:125
* fix: resolve 4 minor code quality issues
GSM8KBenchmark.cs:
- Fix TotalProblems to return 10 (actual sample size) instead of 1319
- Add clarifying comment about full test set size
- Fix typo in problem text: 'How load' -> 'How long' (line 293)
AdaptiveComputeScaler.cs:
- Remove unused generic type parameter T (line 41)
- Class does not use T anywhere, simplified to non-generic
ProcessRewardModel.cs:
- Add diagnostic logging when LLM reward parsing fails (line 234)
- Prevents silent failures that mask model response issues
- Logs first 100 chars of unparseable response for debugging
Resolves PR review comments:
- GSM8KBenchmark.cs:62 (misleading total problems)
- GSM8KBenchmark.cs:293 (typo)
- AdaptiveComputeScaler.cs:41 (unused generic parameter)
- ProcessRewardModel.cs:233 (silent failure)
* revert: remove incorrect generic constraint from mcts
- Remove 'where T : struct, IConvertible' constraint from MonteCarloTreeSearch
- This library uses INumericOperations<T> to handle all numeric type operations
- Generic constraints are not needed and not used by other search algorithms
- Reverts incorrect change from commit bc279aa2
The AiDotNet library design pattern:
- INumericOperations<T> provides type-safe numeric operations
- No constraints needed on generic parameters
- All other search algorithms (BeamSearch, BestFirstSearch, etc.) follow this pattern
* fix: add null safety checks and fix pattern asymmetry in contradiction detector
- Add null check for text1/text2 in HasObviousContradiction (lines 173-174)
- Fix pattern matching bug: use isNotPattern instead of isPattern on line 193
- Add null check for response in ParseContradictionResponse (lines 298-299)
These fixes prevent NullReferenceException and ensure correct negation detection.
* fix: remove duplicate strategy assignment and fix evaluation context in search algorithms
- Remove redundant StrategyUsed assignment in ReasoningStrategyBase (already set on line 139)
- Fix BreadthFirstSearch to evaluate children against original problem (root.Thought) instead of child.Thought
- Fix BestFirstSearch to evaluate children against original problem (root.Thought) instead of child.Thought
This ensures all search algorithms consistently evaluate thoughts in the context of the original query,
matching the correct pattern used in DepthFirstSearch.
* fix: add missing imports, improve error handling, and enhance fallback logic
- Add missing 'using AiDotNet.Helpers;' to BeamSearch, DepthFirstSearch, and BestFirstSearch
- Remove stale generic type parameter documentation from AdaptiveComputeScaler
- Add FormatException handling for non-numeric severity values in ContradictionDetector
- Improve BreadthFirstSearch fallback to return best explored node instead of just root
* fix: add reproducible shuffling and cancellation token support
- Add seeded Random to TrainingDataCollector for reproducible shuffling (seed defaults to 42)
- Replace Guid.NewGuid() with Random.Next() in GetBatches and SplitData methods
- Add CancellationToken parameter to IChatModel.GenerateResponseAsync interface
- Update ChatModelBase and MockChatModel implementations to accept cancellationToken
- Pass cancellationToken to GenerateResponseAsync in ProcessRewardModel
- Add TODO comment for future ILanguageModel.GenerateAsync cancellation token support
* fix: propagate cancellation token to contradiction detector llm calls
- Pass cancellationToken to GenerateResponseAsync in AreContradictoryAsync (line 149)
- Pass cancellationToken to GenerateResponseAsync in AnalyzeContradictionAsync (line 163)
* fix: correct strategy names to match actual implementations
- Change 'ChainOfThought' to 'Chain-of-Thought' (with hyphens)
- Change 'SelfConsistency' to 'Self-Consistency'
- Change 'TreeOfThoughts' to 'Tree-of-Thoughts'
- Remove non-existent 'ChainOfThought-Verified' strategy
- Use 'Chain-of-Thought' for medium-low difficulty (0.3-0.6)
* feat: implement production-ready cancellationtoken support in chat models
- Updated ILanguageModel.GenerateAsync to accept CancellationToken parameter
- Updated ChatModelBase.GenerateAsync to propagate cancellation token through:
- GenerateAsyncCore calls (actual HTTP requests)
- Task.Delay calls (interruptible retry delays)
- Updated GenerateAsyncCore abstract method signature to accept CancellationToken
- Updated all implementations to honor cancellation:
- OpenAIChatModel: Pass token to HttpClient.SendAsync
- AzureOpenAIChatModel: Pass token to HttpClient.SendAsync
- AnthropicChatModel: Pass token to HttpClient.SendAsync
- Updated GenerateResponseAsync to propagate token (no stub checks)
This provides full production-ready cancellation support - HTTP calls can be
cancelled mid-flight, and retry delays are interruptible. No stub
implementations - actual cancellation propagation through the entire call chain.
Resolves unresolved review thread at ChatModelBase.cs:199
* docs: add cancellationtoken xml documentation and fix mockchatmodel signature
- Added <param> documentation for cancellationToken in ILanguageModel.GenerateAsync
- Updated best practices to include CancellationToken usage example
- Fixed MockChatModel.GenerateAsync to accept CancellationToken parameter
- Fixed MockChatModel.GenerateResponseAsync to propagate cancellationToken
This addresses the code review comments about missing XML documentation
and ensures test mocks match the updated interface contract.
