-<P>The <TT>kolmogorov_max_flow()</TT> function calculates the maximum
-flow of a network. See Section <A HREF="graph_theory_review.html#sec:network-flow-algorithms">Network
-Flow Algorithms</A> for a description of maximum flow. The calculated
-maximum flow will be the return value of the function. The function
-also calculates the flow values <I>f(u,v)</I> for all <I>(u,v)</I> in
-<I>E</I>, which are returned in the form of the residual capacity
-<I>r(u,v) = c(u,v) - f(u,v)</I>.
-</P>
-<P><B>Requirements:</B><BR>The directed graph <I>G=(V,E)</I> that
-represents the network must include a reverse edge for every edge in
-<I>E</I>. That is, the input graph should be <I>G<SUB>in</SUB> =

-must map each edge in the original graph to its reverse edge, that is
-<I>(u,v) -> (v,u)</I> for all <I>(u,v)</I> in <I>E</I>.
-</P>
-<P>Remarks: While the push-relabel method states that each edge in <I>E<SUP>T</SUP></I>
-has to have capacity of 0, the reverse edges for this algorithm ARE
-allowed to carry capacities. If there are already reverse edges in
-the input Graph <I><FONT FACE="Courier New, monospace">G</FONT></I>,
-those can be used. This can halve the amount of edges and will
-noticeably increase the performance.<BR><BR><B>Algorithm
-description:</B><BR>Kolmogorov's algorithm is a variety of the
-augmenting-path algorithm. Standard augmenting path algorithms find
-shortest paths from source to sink vertex and augment them by
-substracting the bottleneck capacity found on that path from the
-residual capacities of each edge and adding it to the total flow.
-Additionally the minimum capacity is added to the residual capacity
-of the reverse edges. If no more paths in the residual-edge tree are
-found, the algorithm terminates. Instead of finding a new shortest
-path from source to sink in the graph in each iteration, Kolmogorov's
-version keeps the already found paths as follows:</P>
-<P>The algorithm builds up two search trees, a source-tree and a
-sink-tree. Each vertex has a label (stored in <I>ColorMap</I>) to
-which tree it belongs and a status-flag if this vertex is active or
-passive. In the beginning of the algorithm only the source and the
-sink are colored (source==black, sink==white) and have active status.
-All other vertices are colored gray. The algorithm consists of three
-phases:</P>
-<P><I>grow-phase</I>: In this phase active vertices are allowed to
-acquire neighbor vertices that are connected through an edge that has
-a capacity-value greater than zero. Acquiring means that those vertices
-become active and belong now to the search tree of the current
-active vertex. If there are no more valid connections to neighbor
-vertices, the current vertex becomes passive and the grow phase
-continues with the next active vertex. The grow phase terminates if
-there are no more active vertices left or a vertex discovers a vertex
-from the other search tree through an unsaturated edge. In this case
-a path from source to sink is found.</P>
-<P><I>augment-phase</I>: This phase augments the path that was found
-in the grow phase. First it finds the bottleneck capacity of the
-found path, and then it updates the residual-capacity of the edges
-from this path by substracting the bottleneck capacity from the
-residual capacity. Furthermore the residual capacity of the reverse
-edges are updated by adding the bottleneck capacity. This phase can
-destroy the built up search trees, as it creates at least one
-saturated edge. That means, that the search trees collapse to
-forests, because a condition for the search trees is, that each
-vertex in them has a valid (=non-saturated) connection to a terminal.</P>
-<P><I>adoption-phase</I>: Here the search trees are reconstructed. A
-simple solution would be to mark all vertices coming after the first
-orphan in the found path free vertices (gray). A more sophisticated
-solution is to give those orphans new parents: The neighbor vertices
-are checked if they have a valid connection to the same terminal like
-this vertex had (a path with unsaturated edges). If there is one,
-this vertex becomes the new parent of the current orphan and this
-forest is re-included into the search tree. If no new valid parent is
-found, this vertex becomes a free vertex (marked gray), and it's
-children become orphans. The adoption phase terminates if there are
-no more orphans.</P>
-<P><IMG SRC="figs/kolmogorov_max_flow.gif" NAME="Grafik2" ALIGN=LEFT WIDTH=827 HEIGHT=311 BORDER=0><BR CLEAR=LEFT><B>Details:</B></P>
-<UL>
- <LI><P>Marking heuristics: A timestamp is stored for each vertex
- which shows in which iteration of the algorithm the distance to the
- corresponding terminal was calculated.
- </P>
- <UL>
- <LI><P>This distance is used and gets calculated in the
- adoption-phase. In order to find a valid new parent for an orphan,
- the possible parent is checked for a connection to the terminal to
- which tree it belongs. If there is such a connection, the path is
- tagged with the current time-stamp, and the distance value. If
- another orphan has to find a parent and it comes across a vertex
- with a current timestamp, this information is used.</P>
- <LI><P>The distance is also used in the grow-phase. If a vertex
- comes across another vertex of the same tree while searching for
- new vertices, the other's distance is compared to its distance. If
- it is smaller, that other vertex becomes the new parent of the
- current. This can decrease the length of the search paths, and so
- amount of adoptions.</P>
- </UL>
- <LI><P>Ordering of orphans: As described above, the augment-phase
- and the adoption phase can create orphans. The orphans the
- augment-phase generates, are ordered according to their distance to
- the terminals (smallest first). This combined with the
- distance/timestamp heuristics results in the possibility for not
- having to recheck terminal-connections too often. New orphans which
- are generated in adoption phase are processed before orphans from
- the main queue for the same reason.</P>
-</UL>
-<P><BR><B>Implementation notes:</B></P>
-<P>The algorithm is mainly implemented as described in the PhD thesis
-of Kolmogorov. Few changes were made for increasing performance:</P>
-<UL>
- <LI><P>initialization: the algorithm first augments all paths from
- source->sink and all paths from source->VERTEX->sink. This
- improves especially graph-cuts used in image vision where nearly
- each vertex has a source and sink connect. During this step, all
- vertices that have an unsaturated connection from source are added
- to the active vertex list and so the source is not.
- </P>
- <LI><P>active vertices: Kolmogorov uses two lists for active nodes
- and states that new active vertices are added to the rear of the
- second. Fetching an active vertex is done from the beginning of the
- first list. If the first list is empty, it is exchanged by the
- second. This implementation uses just one list.</P>
- <LI><P>grow-phase: In the grow phase the first vertex in the
- active-list is taken and all outgoing edges are checked if they are
- unsaturated. This decreases performance for graphs with high-edge
- density. This implementation stores the last accessed edge and
- continues with it, if the first vertex in the active-list is the
- same one as during the last grow-phase.</P>
-</UL>
-<P>This algorithm [68, 69] was developed by Boykov and Kolmogorov.
