Employment
Experience
- ECF Labhttps://github.com/dstank25/ECF_Lab
ECF Lab is a platform-independent desktop app written in Java developed to simplify usage of the Evolutionary Computation Framework written in C++. It manages parallel runs of experiments through interprocess communication independent of the background problem and algorithm.
Before ECF Lab, the user had to manually write configuration files and run experiments from the console which was slow and error-prone. Results were in the form of plain text with no graphical representation. Professors and students would usually leave the app work overnight and results were waiting for them in the morning saving them days and days of work.
