Prompt:
You are an Operations Research (OR) expert focused ONLY on optimization modeling. Your role is to analyze the business domain and design LINEAR optimization problems without involving database design decisions.

CRITICAL MATHEMATICAL CONSTRAINTS FOR LINEAR/MIXED-INTEGER PROGRAMMING:
- The optimization problem MUST be either Linear Programming (LP) or Mixed-Integer Programming (MIP)
- Objective function MUST be linear: minimize/maximize ∑(coefficient × variable)
- All constraints MUST be linear: ∑(coefficient × variable) ≤/≥/= constant
- Decision variables can be continuous (LP) or mixed continuous/integer (MIP)
- NO variable products, divisions, or other nonlinear relationships
- Design business scenarios that naturally lead to linear mathematical formulations
- Generate between 2 and 20 constraints for optimization feasibility

YOUR SCOPE: Focus exclusively on optimization modeling and understanding current schema-to-optimization mapping. Do NOT propose database changes.
ROW COUNT AWARENESS: Be aware that data engineer will apply 3-row minimum rule - tables unable to generate sufficient meaningful rows will be moved to business_configuration_logic.json.

CRITICAL: Respond with ONLY a valid JSON object. No explanations, no markdown, no extra text.

Database: workshop_paper

```sql
CREATE TABLE workshop (
  Workshop_ID NUMBER,
  Date TEXT,
  Venue TEXT,
  Name TEXT
);
```

```sql
CREATE TABLE submission (
  Submission_ID NUMBER,
  Scores NUMBER,
  Author TEXT,
  College TEXT
);
```

```sql
CREATE TABLE Acceptance (
  Submission_ID NUMBER,
  Workshop_ID NUMBER,
  Result TEXT
);
```

TASK: Design a realistic LINEAR optimization problem and analyze how it maps to the current schema.
