Hi, Can I disable re-indexing of vertices after one of them is removed? In one of the old thread: http://thread.gmane.org/gmane.comp.lib.boost.user/10551/focus=10552 Doug said: " Vertex and edge indices are a weak point in the BGL. It seems like they should be automatically updated, but that can't be done efficiently. We have a partial solution (a graph type that is reasonably good all-around and does automatic (re-)indexing), but it's not ready for release yet." I am using release 1.33.1. Is this re-indexing released?(I assume so, from my simple trial) But, is there any way of enabling /and disabling re-indexing? Interestingly, my application needs re-indexing disabled, even though some vertices or edges are removed. Thanks, Shufei
