     178Makefile Variables
     179==================
     180
     181Some Makefile variables are reserved by the GNU Coding Standards for
     182the use of the "user" - the person building the package. For instance,
     183CXX and CXXFLAGS are such variables, and have the same meaning as
     184explained in the previous section. These variables can be set on the
     185command line when invoking `make' like this:
     186`make [VARIABLE=VALUE]...'
     187
     188WARNINGCXXFLAGS is a non-standard Makefile variable introduced by us
     189to hold several compiler flags related to warnings. Its default value
     190can be overridden when invoking `make'. For example to disable all
     191warning flags use `make WARNINGCXXFLAGS='.
     192
     193In order to turn off a single flag from the default set of warning
     194flags, you can use the CXXFLAGS variable, since this is passed after
     195WARNINGCXXFLAGS. For example to turn off `-Wold-style-cast' (which is
     196used by default when g++ is detected) you can use
     197`make CXXFLAGS="-g -O2 -Wno-old-style-cast"'.

     249This group contains the heap structures implemented in LEMON.
     250
     251LEMON provides several heap classes. They are efficient implementations
     252of the abstract data type \e priority \e queue. They store items with
     253specified values called \e priorities in such a way that finding and
     254removing the item with minimum priority are efficient.
     255The basic operations are adding and erasing items, changing the priority
     256of an item, etc.
     257
     258Heaps are crucial in several algorithms, such as Dijkstra and Prim.
     259The heap implementations have the same interface, thus any of them can be
     260used easily in such algorithms.

     454@defgroup min_mean_cycle Minimum Mean Cycle Algorithms
     455@ingroup algs
     456\brief Algorithms for finding minimum mean cycles.
     457
     458This group contains the algorithms for finding minimum mean cycles
     459\ref clrs01algorithms, \ref amo93networkflows.
     460
     461The \e minimum \e mean \e cycle \e problem is to find a directed cycle
     462of minimum mean length (cost) in a digraph.
     463The mean length of a cycle is the average length of its arcs, i.e. the
     464ratio between the total length of the cycle and the number of arcs on it.
     465
     466This problem has an important connection to \e conservative \e length
     467\e functions, too. A length function on the arcs of a digraph is called
     468conservative if and only if there is no directed cycle of negative total
     469length. For an arbitrary length function, the negative of the minimum
     470cycle mean is the smallest \f$\epsilon\f$ value so that increasing the
     471arc lengths uniformly by \f$\epsilon\f$ results in a conservative length
     472function.
     473
     474LEMON contains three algorithms for solving the minimum mean cycle problem:
     475- \ref Karp "Karp"'s original algorithm \ref amo93networkflows,
     476  \ref dasdan98minmeancycle.
     477- \ref HartmannOrlin "Hartmann-Orlin"'s algorithm, which is an improved
     478  version of Karp's algorithm \ref dasdan98minmeancycle.
     479- \ref Howard "Howard"'s policy iteration algorithm
     480  \ref dasdan98minmeancycle.
     481
     482In practice, the Howard algorithm proved to be by far the most efficient
     483one, though the best known theoretical bound on its running time is
     484exponential.
     485Both Karp and HartmannOrlin algorithms run in time O(ne) and use space
     486O(n<sup>2</sup>+e), but the latter one is typically faster due to the
     487applied early termination scheme.
