#13374: Boykov Kolmogorov warning with float
------------------------------+-------------------------------
 Reporter:  cyril.novel@…     |      Owner:  Jeremiah Willcock
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  graph
  Version:  Boost 1.63.0      |   Severity:  Problem

------------------------------+-------------------------------
 In boykov_kolmogorov_max_flow.hpp, some values put in property_map are
 integer :

 {{{
 l.176             put(m_res_cap_map, from_source, 0);
 l.190              put(m_dist_map, current_node, 1);
 l.196              put(m_res_cap_map, to_sink, 0);
 l.202              put(m_dist_map, current_node, 1);
 l.208              put(m_res_cap_map, from_source, 0);
 l.217            put(m_dist_map, current_node, 1);
 l.228            put(m_dist_map, current_node, 1);
 }}}

 It causes a C4244 warning in property_map/property_map.hpp (l.310) when
 using floating distance and floating cost. An easy way to prevent this is
 to patch as follow:

 {{{
 l.176             put(m_res_cap_map, from_source, tEdgeVal(0));
 l.190              put(m_dist_map, current_node, tDistanceVal(1));
 l.196              put(m_res_cap_map, to_sink, tEdgeVal(0));
 l.202              put(m_dist_map, current_node, tDistanceVal(1));
 l.208              put(m_res_cap_map, from_source, 0);
 l.217            put(m_dist_map, current_node, tDistanceVal(1));
 l.228            put(m_dist_map, current_node, tDistanceVal(1));
 }}}
