Subject: [geometry] Finding a boost::equal simplified polygon

I am looking for a method for finding boost::euqual polygons. The problem I am
facing is that my code creates unnecessarily complex polygons of the type
where the vertex D sits inside the polygon. Technically the polygon
(A,B,C,D,E,F,G,A) is boost::equal to the polygon (A,B,C,F,G,A). Could anybody
point me to how I could write/get/find/have an efficient way to get the
'simplified' (A,B,C,F,G,A) from the 'complicated' (A,B,C,D,E,F,G,A)?
Note though that the 'spike' to the interior can have several (coinciding)
My current approach checks all vertices for colocation and then computes the
area of the ring spanned by all the interim vertices ((C,D,E) in the above
example). Does anybody have a better idea?
