+# Quine-McCluskey Algorithm
+
+## Overview
+
+The Quine-McCluskey algorithm (also known as the tabular method) is a systematic method for minimizing Boolean functions. It was developed by Willard V. Quine and Edward J. McCluskey in the 1950s. Unlike Karnaugh maps (K-maps), which are visual and limited to about 4-6 variables, the Quine-McCluskey algorithm can handle any number of variables and is well-suited for computer implementation.
+
+## Algorithm Overview
+
+The Quine-McCluskey algorithm consists of two main steps:
+
+### Step 1: Finding Prime Implicants
+
+1. **List all minterms**: Start with the minterms (product terms) where the function equals 1
+2. **Group by number of 1s**: Organize minterms by the number of 1s in their binary representation
+3. **Combine adjacent groups**: Compare minterms that differ by only one bit position
+4. **Mark combined terms**: Terms that are combined are marked as used
+5. **Repeat**: Continue combining until no more combinations are possible
+6. **Prime implicants**: Unmarked terms after the process are prime implicants
+
+### Step 2: Selecting Essential Prime Implicants
+
+1. **Create prime implicant chart**: List all prime implicants and the minterms they cover
+2. **Identify essential prime implicants**: Prime implicants that are the only ones covering a particular minterm
+3. **Select minimal cover**: Choose the minimum set of prime implicants to cover all minterms
+
+## Advantages over Karnaugh Maps
+
+- **Scalability**: Can handle any number of variables (K-maps are limited to 4-6 variables)
+- **Systematic approach**: Can be easily programmed and automated
+- **Precision**: Eliminates human error in pattern recognition
+- **Consistency**: Always produces the minimized form
+
+## Examples in This Directory
+
+### qm_3var.v
+Simple 3-variable function demonstrating basic minimization.
+- Minterms: 0,1,2,5,7
+- Minimized: a'b' + ac + bc
+
+### qm_4var.v
+Standard 4-variable function example.
+- Minterms: 0,1,2,5,6,7,8,9,14
+- Minimized: a'b' + b'c' + ac'd
+
+### qm_4var_complex.v
+More complex 4-variable function.
+- Minterms: 1,3,4,5,6,7,10,12,13
+- Minimized: a'c + ab' + bc'd + a'bd'
+
+### qm_5var.v
+5-variable function demonstrating QM's advantage for functions with many variables.
+- Minterms: 0,1,4,5,8,9,12,13,16,17,20,21
+- Minimized: a'c'e' + a'c'd' + ab'c'
+
+### qm_majority.v
+Majority function implementation (outputs 1 if at least 2 of 3 inputs are 1).
+- Minterms: 3,5,6,7
+- Minimized: ab + ac + bc
+
+### qm_xor_like.v
+Complex 4-variable function with limited simplification opportunity.
+- Minterms: 1,2,4,7,8,11,13,14
+- Note: This function requires all 8 product terms (minimal simplification possible)
+
+### qm_prime_implicant.v
+Example demonstrating prime implicant selection.
+- Minterms: 0,2,5,6,7,8,10,12,13,14,15
+- Minimized: ab + ac + b'c' + a'd
+
+## Comparison with Karnaugh Maps
+
+Both Quine-McCluskey and Karnaugh maps solve the same problem (Boolean function minimization) but differ in approach:
+
+| Feature | Karnaugh Map | Quine-McCluskey |
+|---------|--------------|-----------------|
+| Method | Visual/Graphical | Tabular/Algorithmic |
+| Variable Limit | 4-6 variables | Unlimited |
+| Ease of Use | Intuitive for humans | Better for computers |
+| Error Prone | Yes (pattern recognition) | No (systematic) |
+| Automation | Difficult | Easy |
+
+## Applications
+
+- **Digital circuit design**: Minimizing logic gates in hardware
+- **FPGA/ASIC design**: Reducing resource usage
+- **Compiler optimization**: Boolean expression simplification
+- **Logic synthesis**: Automated design tools
