- June 2019: Congratulations everyone! 🍾🎉DHE has successfully tackled its largest circuit to date: ALU2. ALU2 uses 293 gates to perform its' function and would require 323 extra gates to perform concurrent error detection (CED) using duplication and comparison. A solution designed by DHE requires only 66 gates overhead to perform full CED, this is 20\% of the conventional solution's overhead! Thanks to your efforts, DHE has also designed a Totally Self-Checking version of ALU2 (the first ever) requiring only 137 gates overhead!
- April 2019: DHE doubles it's server capacity and welcomes all crunchers to a big push as it tackles the largest circuits in its history!
- April 2019: DHE begins synthesising fault-secure (FS) only circuits from the MCNC'91 benchmark suite. FS circuits guarantee an error signal accompanying incorrect output due to a single fault. Whilst previous state-of-the-art techniques require 56% overhead, DHE results so far require an average 5% overhead! All results can be visualised in the `Better than Human' Hall of Fame where each solution has been named by the owner of the islands who found it.
January 2019: DHE is the first automatic method to synthesise totally self-checking (TSC) circuits. These offer the highest safety guarantee as correct operation is guaranteed until an error is signalled. Silent fault accumulation is avoided as TSC circuits flag all faults in checking logic as well. Thanks to our crunchers from the distributed computing community we have been able to produce TSC circuits with less than a third overhead than other techniques whilst offering better protection!

- October 2018: The winner of the DHE Badge Design Competition is Simone!👏👏👏👏
- August 4 2018: DHEP Badge Design Competition!
Badges will be awarded to those making exceptional contributions to our project.
Calling all talented designers to design the badges that will be handed out at DHE! The winner will be announced here, have a special contribution badge (of their own design!), and be acknowledged here as well as your work being visible and admired by everyone in the community!
We are looking for badges to be attractive, eye-catching, and would be great if they represent in some way the project and activity being rewarded. There will be badges for participating in alpha & beta periods, for credit levels, going above and beyond to help the project in special ways, for islands originating certain numbers of 'best of all island' solutions, and many more...
All designs welcome at M.Garvie@sussex.ac.uk until August 20th!PS: For ideas from other projects' badges check this and this.
- July 26 2018: DHEP is now available on BOINC at http://dhep.ga/boinc.
- June 15 2018: Genetic strains analysis is now live showing in depth data on population dynamics and genotypic variation across islands.
- June 9 2018: After a brief glitch, the circuit viewer and simulator is now working again so you can view and try out solutions (such as this) as they're being evolved, as well as all of those in the 'Better than human' Hall of Fame.
- June 2 2018: We have evolved the largest TSC benchmark so far: m1 with 64 gates. The best current solution only needs 38% duplication overhead and is dropping almost daily.
- May 30 2018: We thought Hotbrain was good with its' 10 extra gates instead of the 72 required by standard methods. Lucy, evolved a few days ago, only needs 8! This is equivalent to 11% duplication overhead. Unprecedented for such a Totally Self-Checking circuit. How smart can these get?
- May 28 2018: Interesting TED talk on Generative Design. Be part of this at DHEP!
- May 24 2018: DHEP is now fully live!
- May 11 2018: The Distributed Hardware Evolution Project is now in Beta. Early birds welcome!
