The quota allocation for CCF NOI in each province (including municipalities and autonomous regions, hereafter collectively referred to as "provinces") consists of two categories: **Category A** and **Category B**. ↵
- **Category A** represents the basic contestant quota, with each province receiving an equal number of slots. ↵
- **Category B** represents the reward quota for outstanding performance, allocated by the organizing committee to provinces with exceptional NOI participation based on predefined criteria. ↵
↵
All contestants in Categories A and B must be selected by provincial organizing units through procedures reviewed and approved by the national organizing committee. Contestants directly assigned without undergoing the selection process will be deemed ineligible. ↵
↵
### **Detailed Quota Allocation Plan** ↵
↵
#### **I. Category A** ↵
Each province receives **5 Category A slots**, with at least **1 slot reserved for a female contestant**. ↵
↵
#### **II. Category B** ↵
The **Category B** quota for each province comprises three components: **B1**, **B2**, and **B3**. Let the total Category B quota be **S** (where **S = 150**). The calculation methods are as follows: ↵
↵
1. **B1 (Popularization Component, 50%)** ↵
Calculated based on the number of participants in the latest NOIP (National Olympiad in Informatics in Provinces): ↵
$$↵
B1 = S \times 50\% \times \left(\frac{\text{Number of NOIP participants in the province}}{\text{Total national NOIP participants}}\right)↵
$$ ↵
↵
2. **B2 (Overall Performance Component, 30%)** ↵
- For each province, the latest NOIP scores are sorted in **descending order** and divided into **K1 segments** (where **K1 = 5**). The average score of each segment is taken as the province’s representative scores. ↵
- All representative scores nationwide are ranked, and the top **S × 30%** (rounded down) are selected. ↵
- A province’s B2 quota equals the number of its representative scores within the top **S × 30%**. ↵
- If tied scores occur at the cutoff, all tied scores are included, and the quota is proportionally adjusted based on the actual total (see example below). ↵
↵
**Example**: If the predetermined B2 quota is 45, but including tied scores results in 47 participants, and a province has **n** representative scores among them, its adjusted B2 quota is: ↵
$$↵
\text{B2 quota} = 45 \times \left(\frac{n}{47}\right)↵
$$ ↵
↵
3. **B3 (Excellence Component, 20%)** ↵
- For each province, the top **K2 scores** (where **K2 = 5**) from the latest NOIP are selected as its outstanding scores. ↵
- All outstanding scores nationwide are ranked, and the top **S × 20%** (rounded down) are selected. ↵
- A province’s B3 quota equals the number of its outstanding scores within the top **S × 20%**. ↵
- Tie adjustments follow the same method as B2. ↵
↵
4. **Provincial Limits for Category B** ↵
- The total Category B quota for a province ( **B = B1 + B2 + B3** ) must not exceed **5%** of its latest NOIP participants with non-zero scores. ↵
- Additionally, no province may receive more than **12 Category B slots**. ↵
↵
#### **III. Notes** ↵
1. The final Category B quota for each province is **rounded to the nearest integer**. ↵
2. Only **high school contestants with non-zero scores** in the latest NOIP are counted for calculations. ↵
3. The CCF NOI Scientific Committee reserves the right to interpret and finalize this plan. ↵
