- Assumptions made

## 1.7 Thesis Organization
"The remainder of this thesis is organized as follows.
Chapter 2 reviews... Chapter 3 describes... Chapter 4 presents...
Chapter 5 discusses... Chapter 6 concludes..."

Chapter 2: Literature Review

Purpose: Comprehensive survey — position your work in the field.

Structure:

## 2.1 Overview of Research Area
[2-3 pages]
- History and evolution
- Current state of the art
- Key milestones

## 2.2 Theoretical Foundations
[3-5 pages]
- Core concepts and definitions
- Mathematical foundations
- Key theorems/properties

## 2.3 Related Work Taxonomy
[2-3 pages]
- Group A: [Approach name] — papers [1,3,5]
- Group B: [Approach name] — papers [2,4]
- Group C: [Approach name] — papers [6,7]

## 2.4 Detailed Analysis of Key Works
[8-12 pages]
For each important paper:
- Problem addressed
- Method proposed
- Strengths
- Limitations
- How our work differs

## 2.5 Comparison Table
| Paper | Year | Problem | Method | Dataset | Result | Limitation |
|-------|------|---------|--------|---------|--------|------------|
| ...   | ...  | ...     | ...    | ...     | ...    | ...        |
