Detailed Description

template<typename Graph = lemon::SmartGraph>
class minlca::MinLCAGreedyLeastCost< Graph >

Greedy nearest colour approach for MinLCA.

Each vertex is assigned the colour which least increments the cost. Read the report of Bachelor's Thesis Algorithms for the linear colouring arrangement problem for more information.
