Algorithms Analysing of Eight Queens Problem

Problem Intro The eight queens problem is based on Chess, it's for determining how to place 8 queens on a chessboard of size 8 × 8, and make sure any of the queens cannot capture the other 7 queens. To get this approach, any of two queens cannot be at the

pyfirmata is a package that can make a connection between Arduino and Python, this post is a brief tutorial on using pyfirmata and create an interesting small project. Installing and Loading Firmata Install Script pip install pyfirmata Before we can code with Python, we need to load a format framework

Three Examples in solving Synchronization

Note: This post is summary of learning Operation System Internals and Design Principles (Ninth Edition) Chapter 5 As we know the Peterson Algorithms that allows two or more (actually it can) processes to share a single-use resource without conflict by using the busy waiting method to solve Mutual Exclusion Problems.

Implementing Convolutional Neural Networks with Keras

Implementing Convolutional Neural Networks with Keras

Introduction Keras is a Deep Learning library for Python, after learning Intro to Neural Networks and Intro to Convolutional Neural Networks from Victor Zhou, These two posts produce implementations of Neural Networks and CNN from scratch (using only NumPy), To refresh the knowledge while reviewing it, I decided to write

Implementing Peterson Algorithm with Python

Peterson's algorithm is a concurrent programming algorithm for mutual exclusion that allows two or more processes to share a single-use resource without conflict. Implementing Peterson algorithm is straightforward, here is the pseudocode in C style. /* Globally Init */ int flag[2] = {false, false}; int turn = 0; void enter_region (int process)
