Long time ago in 1986 I made my student thesis on RRQR, where had developed algorithm on how to make it efficiently and correctly. After that, I switched to work on various projects not connected with the subject. Recently, I recall that work in context of page rank calculation and found that so far it looks like no final solution developed for RRQR. So I am wondering if there is any interest in that problem (I guess it is) and what to do with my results? Any advice from this community?

Thanks!
