Low-Autocorrelation Binary Sequences Problem

Puzzle

Crowd-sourcing

A crowd-sourcing EvoDE server has been implemented to facilitate experimentation and push the frontiers on finding new best-known values for the labs problem. The lssOrel solver is running within a web browser. Thus, this problem can be solved on various devices that are in different locations.
