one-dimensional distortion of rubber band algorithm

Question

Problem: I have a database result set of n. I want to have k < n index links to the results on a html page. There should be more index links near the cursor, have the user forward +5 is more probable than to forward +50

Idea is to have a number line on a rubber band with markings, if I put a weight on the cursor point and view from above I should have the index points.

Is there an easy algorithm for this?

Same problem would be for an index to forum messages.

What are 'index links to the results'? What does 'forward' mean in this context? — le_m, May 05 '17 at 21:33
If you have a resultpage_1.html up to resultpage_1000.html, s.th. like 10 — weberjn, May 05 '17 at 21:42
You are talking about pagination. Your can't show all page links, so you want to show the first, last and those close to the active page, correct? — le_m, May 05 '17 at 21:48
In the sample in the image I'd like to link to 1,3,4 maybe 8, and ten — weberjn, May 05 '17 at 21:50
no link to the first element 0? Perhaps you could include a good / expected output for the given pagination in your question. — le_m, May 05 '17 at 21:51
