Computer Science Project: Dynamic Programming Using Golang 1. Project Title

Optimizing Algorithm Efficiency Through Dynamic Programming in Go (Golang)

2. Project Background

Dynamic Programming (DP) is a key computer science technique used to optimize complex recursive algorithms by storing intermediate results and avoiding redundant computation. This approach drastically improves performance, especially for problems involving overlapping subproblems and optimal substructure, such as Fibonacci sequences, knapsack optimization, grid pathfinding, and sequence alignment.

This project demonstrates the application of DP concepts using the Go programming language with both Top-Down (Memoization) and Bottom-Up (Tabulation) approaches.

3. Project Objective

• To implement and compare recursive, memoized, and bottom-up DP solutions in Golang.

• To analyze time and space complexity improvements compared to brute-force algorithms.

• To apply DP patterns to real-world problems such as optimization, shortest path, and resource allocation.

Performance Benchmarking Algorithm Variant Time Complexity Result Recursive (brute force) O(2ⁿ) Slow, exponential Memoization (Top-Down) O(n) Improved significantly Tabulation (Bottom-Up) O(n) Fastest + stable memory usage 9. Key Learning Outcomes

• Understanding how DP reduces computational cost using stored states.

• Transitioning from recursion-based thinking to iterative optimization.

• Applying DP to real-world logic such as resource optimization and decision modeling.

• Mastering Golang memory model (stack vs heap) when storing DP tables.

10. Conclusion

Through memoization and tabulation, the project demonstrates measurable efficiency gains and builds foundational skills applicable to system optimization, competitive programming, and technical interviews.
