Sample Master-Level Programming Assignment Questions and Solutions

Assignment Question 1: Distributed Systems – Fault-Tolerant Key-Value Store

Design and implement a fault-tolerant distributed key-value store using the Raft consensus algorithm. The system must support leader election, log replication, and safety guarantees. Demonstrate how your implementation handles node failure and ensures consistency when two or more nodes temporarily lose connectivity.

Expert Solution (Summary):
Our expert built a Python-based distributed architecture using asyncio and RPC-style communication. The core solution involved:

1. Leader Election:
   Each node maintains randomized election timeouts, triggering an election if no heartbeat is received. The candidate node solicits votes from peers, ensuring it becomes a leader only if it holds the latest committed log.

2. Log Replication:
   The leader appends new entries to its log and dispatches AppendEntries RPCs to follower nodes. A commit occurs once the leader confirms majority replication. The system ensures idempotence and minimizes divergence using term-based log indexing.

3. Failure Handling:
   During simulated node failure, followers continued to operate on committed log entries. When the failed node rejoined the cluster, it automatically synchronized logs using Raft’s conflict resolution mechanism.

This end-to-end demonstration reflects the precision of our programming assignment help USA, enabling students to learn techniques used in production-grade distributed systems.

Assignment Question 2: Machine Learning Engineering – Custom Autograd Engine

Implement a miniature deep-learning autograd engine capable of handling forward and backward passes with computational graphs. The engine must support matrix operations, element-wise operations, and gradient accumulation. For testing, build a two-layer neural network and train it on synthetic data.

Expert Solution (Summary):
Our expert created a lightweight autograd module in Python featuring:

1. Tensor Class:
   Encapsulates data, gradient storage, and node relationships. Supports broadcasting, dot products, and non-linear activation functions.

2. Graph Construction:
   Each operation creates a node with references to parent tensors. Backward propagation traverses the graph in reverse topological order, computing gradients using the chain rule.

3. Neural Network Test:
   A two-layer feedforward network (ReLU activation) was trained using gradient descent. After 300 iterations, the model achieved convergence toward the synthetic target function, demonstrating correctness of the autograd pipeline.

Assignments like these illustrate how our programming assignment help USA enables learners to deeply understand advanced computation and engineering workflows.
