To update a RMQ I think you need to re-process that bucket again. You can made a Range Sum Query with "RMQ", but it would be better and simpler to uso a Fenwick Tree. There are some good articles about it on topcoder: http://www.topcoder.com/tc?d1=tutorials&d2=lowestCommonAncestor&module=Static http://community.topcoder.com/tc?module=Static&d1=tutorials&d2=binaryIndexedTrees
You mean answer RMQ problems where the array can be changed? If so, I recommend you to learn segment tree.
