Gen Algo CLI

A nodeJs based CLI for running a genetic algorithm to optimize hydrogen production from a given flare gas using a Steam Methane Reformer

Build Instructions

cd path/to/repo
npm run build
npm link

• The first npm command builds the CLI; compiling the typescript code down to javascript and also creates some directories and files to allow the CLI operate properly
• The second npm command make the package available at a global level (kinda like installing it globally). This allows you to run the command gen-algo to use the application

or

gen-algo help

To update your configuration, you can copy the file at $HOME/.gen-algo/config/defaultConfig.yaml and make changes to it. Then supply the path of the changed file to the update-config command

cp $HOME/.gen-algo/config/defaultConfig.yaml path/to/copy/file/to
gen-algo update-config -p path/to/copied-and-updated/config-file

After running the algorithm, the results are written to an output.txt file in the current working directory
