The Objective Of This Assignment Is To Apply the Concepts Of Threading

The objective of this assignment is to apply the concepts of threading by developing a simple C++ Posix threads program to discover the surroundings and the shortest path in a 2D maze. This assignment requires you to write a multi-threaded C/C++ “Pathfinder” program to discover the surroundings of a jungle maze. Each [x, y] location in the maze represents a ‘grid area’ of the jungle terrain. You're provided with header files that contain necessary methods to facilitate your implementation. Your task is to write the main.cpp file that utilizes these functions to produce the required output, which must exactly match the specifications in the provided document. It is crucial to follow the instructions strictly and use the given header files appropriately to replicate the expected output precisely.

In this assignment, the core objective is to implement a multi-threaded pathfinding algorithm in C++ using Posix threads to explore a maze and identify the shortest path within it. This involves understanding and applying threading concepts to optimize maze exploration, which is a common challenge in concurrent programming and AI pathfinding tasks. The problem is set in a 2D maze where each cell is a grid representing jungle terrain, and the program must efficiently discover surroundings and find a jungle path.

Implementing such a program requires careful design to ensure thread safety, proper synchronization, and efficient communication between threads. Given that header files are provided containing essential methods, the focus shifts to integrating these functions into the main application code—main.cpp— to achieve the desired output. The header files encapsulate functions for maze exploration, obstacle detection, and path recording, thus simplifying the development process by providing ready-to-use algorithms and utilities.

The first step in developing the program involves initializing the maze environment by calling the provided functions to set up the terrain grid. The next critical step is leveraging threading to concurrently explore various sections of the maze, minimizing exploration time. Threads should be synchronized to prevent race conditions during shared data access, especially when marking explored cells or updating the shortest path.

A typical strategy used in such tasks is a shortest path algorithm, such as Dijkstra's or A* algorithm, but adapted for multi-threaded execution. The threads collectively work on discovering adjacent cells, updating their knowledge of surroundings, and eventually converge on the shortest route. The program must also accurately log each exploration step, ensuring the final output is identical to the expected output detailed in the provided document.

Finally, the program should present the shortest route once discovered, using the functions from the headers to output the path correctly. Strict adherence to the output format is vital for successful execution matching the specified results.

This task not only enhances understanding of threading concepts but also demonstrates practical application in robotics, AI navigation, and complex problem-solving environments. By integrating concurrent programming with maze exploration algorithms, students can appreciate the importance of efficient resource utilization and synchronization in software development targeting real-world, multi-threaded applications.
