Ask HN: What are licenses for algorithm-design articles similar to GPL

As an algorithm designed, I am often compelled to write articles about how to solve non-trivial algorithmic problems.

I would like my ideas to be disseminated/used/improved and yet my original authorship acknowledged.

For source code, this is achieved with a license like GPL.

But what would be an equivalent for algorithm descriptions (in plain English)?

Thanks, --Petar
