This uses a bit flag to differenciate between small and big components
and keeps the ids for both. This makes it possible to give better
error messages.
table plugins.
Make bearing range configurable by adding a comma-separated second part
to the bearing paramenter, like so:
b=<bearing:0-359>(,<range:0-180>)
If no range is supplied, it defaults to +/- 10 degrees.
With C++11 the stdlib gains:
- `std::stoi` function family to convert from `std::string` to integral type
- `std::to_string` to convert from number types to `std::string`
The only reason for hand-writing the conversion code therefore is
performance. I benchmarked an `osrm-extract` with the hand-written code
against one with the stdlib conversion features and could not find any
significant difference (we switch back and forth between C++ and Lua,
shaving off a few us in conversion doesn't gain us much).
Formatting arithmetic types in the default format with given precision
requires streams, but is doable in a few lines of idiomatic stdlib code.
For this, there is now the following function template available:
template <Arithmetic T, int Precision = 6>
inline std::string to_string_with_precision(const T);
that requires integral or floating point types and returns a formatted
string in the defaukt format with the given precision applied.
In addition this completely rips out Boost.Spirit from the `casts.hpp`
header, resulting in faster compile times.
Boom!

We do not want to parallelize there, as node should be used for
parallelizing the user requests onto multiple processes.
remove empty unit test
remove compiler directives
move trip related files from routing_algorithms to algorithms
run clang-format on files
fix all std::size_t related issues
improve code by adding std::move()s
clean up includes
fixing several code stye and improvement issues
add several small code improvements
return single scc in SplitUnaccessibleLocations() when theres only one
change ComputeRoute() to return an InternalRouteResult by value
improve some code style issues
Problem:
- old solution was slow
- depending on the result of TarjanSCC, new distance tables and new phantom node vectors were created to run tsp on it
Solution:
- dont create new distance tables and phantom node vectors
- pass an additional vector with the information which locations are in the same component and ignore all others
fix bug for scc split computation
add farthest insertion algorithm for round trip
farthest insertion: always add the node that add the biggest distance to the total route
farthest insertion: remove total distance computation and compute only diff instead
