This example shows a very simple evolutionary algorithm.
The program starts with one guess, creates several mutated children, and keeps the better ones.
Over time, the guess improves until it reaches the target number.

Tiny Transformer-Style Attention Example

What this example teaches :

This tiny demo shows the core transformer idea:

1. Each earlier word has a key

This helps decide whether the word is important.

2. Each earlier word also has a value

This carries useful meaning.

3. The current position ...

Beginner Neural Network in C — A Tiny Perceptron That Learns OR

this example teaches:

inputs
weights
bias
weighted sum
activation function
training from examples
error correction

What is the neural network doing?

This tiny network receives two inputs:

x1
x2

It computes:

sum = x1*w1 + x2 ...

Solves linear equations using Gaussian elimination

Example input for the system:

2x + y - z = 8
-3x - y + 2z = -11
-2x + y + 2z = -3

you would enter:

N = 3

Row 1: 2 1 -1 8
Row 2: -3 -1 2 -11
Row 3: -2 1 2 -3

An interactive function graph plotter

You can type expressions like:

sin(x)
cos(x)
x*x
x^3
1/x
sin(x)*x
sqrt(abs(x))
exp(sin(x))
