id summary reporter owner description type status milestone component version severity resolution keywords cc 8427 Johnson APSP documentation is inaccurate Luis G. Torres Jeremiah Willcock "Regarding documentation at http://www.boost.org/doc/libs/1_53_0/libs/graph/doc/johnson_all_pairs_shortest.html The description of the function's named parameter weight_map specifies that the WeightMap's value must be ""addable"" to the value type of the DistanceMap; this is unnecessarily restrictive, however, because the function also allows the user to specify the DistanceCombine function (which only ''defaults'' to addition). It seems that the documentation's requirement for WeightMap's value type to be Addable should be removed." Bugs closed To Be Determined graph Boost 1.53.0 Cosmetic fixed johnson
