It doesn't get more open source then this. Geert Johan one of the lead devs for Guldencoin is building a simulator to test algorithm changes for our test environment.
People have been asking for more feedback from the devs..
I am currently working hard on the difficulty simulator; a tool that allows us to test difficulty re-adjustment algorithms against real-world situations.
This tool is very important to make sure our development on the new algo is supported by results.
I thought it might be a good idea to share this experience with everyone here.
