01
范围与辨析
需公开变量、约束、目标函数和 solver 设置；通用最大似然概念仍归 lookup/ML，本条目聚焦整数优化实现。
02
核心机制与研究判断
核心机制
- binary decision variables
- syndrome constraints
- general-purpose solver
- exact or relaxed objective
适用与评测约束
- Noise Level
- must be declared
- Execution Mode
- batch or online must be declared
- Hardware Sensitivity
- latency and parallelism must be measured
- Input Representation
- syndrome or detector model specific
- Benchmark Comparability
- requires code noise syndrome hardware tuple
