lifesim's Introduction

Lifesim

This project was something I've been working on just for fun. The premise of this project would assume stocks can be predicted based on market trends, which is not necessarily true as stocks are affected by millions of factors outside the representation of the historical values of the stock market. This is only going to be accurate within a reasonable margin of error and may not be accurate at all.

Execution

To run the genetic algorithm, run:

make build run LOG_LEVEL=INFO

Here is example output for GOOG stock over 100 generations with no genetic drift using default natural constants.

[INFO][4:29:23][lifesim/genetics/evolution.cc:28]: Prediction: 227694.027408 (stock will go up)

Observe from the above simulation that each generation does improve on the predictive capability of the model. However, it can never reach 100% as each prediction is only based on historical trends.

Confidence intervals are only to be interpretted within that context.

Each generation takes about 1/3 of a second.
