What are Optimal Golumb Rulers?

What would solving OGR actually be good for?

If Golomb Rulers up to 150 marks are already known, why are we doing this?

Is there a prize for winning OGR?

What is the total number of stubs/nodes in OGR-24 or OGR-25?

What is the most optimal ruler found by d.net so far?

Tell me about the total project percentage complete and Phase 1 and Phase 2?

Client and proxy answers in this category:
What minimum client and proxy versions are needed for OGR?
the personal proxy's completed count jumps by irregular amounts for completed stubs.
why is OGR disabled on my machine? (It runs OGR elsewhere.)
Why can't I get any OGR blocks sometimes?
How does the client search for OGRs?

Speed answers in this category:
Why do some stubs go faster than others? My stub OGR stub takes too long! My OGR stub has stopped progressing at 1 or 2%!
Why did I receive a very large/small OGR-25 stub?

My client is switching between projects instead of working only on my first choice
I'm confused about keys, stats units, nodes, stubs, packets, blocks, work units,...
Packets take too long to complete on my computer. They should be smaller!
