+# Phase 11 Plan 04: 权重网格搜索优化
+
+## Summary
+
+实现权重网格搜索优化功能，通过5种预定义权重配置批量回测，找出最优权重配置，提升算法预测准确性。
+
+## Changes
+
+### Model: _optimizeWeightsGridSearch 方法
+
+在 `application/admin/model/History.php` 新增私有方法，实现权重网格搜索优化：
+
+- **5种预定义配置**：
+  - 遗漏优先型：omit_regression=0.25（最高）
+  - 转移概率优先型：transition_prob=0.25（最高）
+  - 走势方向优先型：trend_direction=0.25（最高）
+  - 平衡型：各维度权重较均衡
+  - 组合特征优先型：combination=0.20（最高）
+
+- **优化目标**：综合得分 = hit_rate * 0.6 + ndcg_5 * 100 * 0.4
+
+- **超时保护**：默认60秒，超时后停止剩余配置测试，返回已完成结果
+
+- **返回结构**：
+  ```php
+  [
+    'best_weights' => [],      // 最优权重配置
+    'best_hit_rate' => float,  // 最优命中率
+    'best_ndcg' => float,      // 最优NDCG
+    'best_combined_score' => float,  // 最优综合得分
+    'all_results' => [],       // 所有配置测试结果（按得分降序）
+    'periods' => int,
+    'backtest_count' => int,
+    'timeout_seconds' => int,
+    'timed_out' => bool,       // 是否超时中断
+    'elapsed_time' => float    // 实际耗时
+  ]
+  ```
+
+### Controller: optimizeWeights 接口
+
+在 `application/admin/controller/History.php` 新增公开方法：
+
+- **参数验证**：
+  - periods：统计期数，范围50-500，默认200
+  - backtest：回测期数，范围10-100，默认30
+  - timeout：超时秒数，范围10-120，默认60
+
+- **超时警告**：超时时返回警告消息和已完成测试数量
+
+- **权限配置**：已添加到 noNeedRight 数组
+
+## Verification
+
+```bash
+# grep 验证
+grep -n "_optimizeWeightsGridSearch" application/admin/model/History.php
+# 结果：3924行，方法签名存在
+
+grep -n "optimizeWeights" application/admin/controller/History.php
+# 结果：25行(noNeedRight)、506行(方法定义)、526行(方法调用)
+```
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None.
