@Generated public final class RoutingSearchParameters extends com.google.protobuf.GeneratedMessage implements RoutingSearchParametersOrBuilder
Parameters defining the search used to solve vehicle routing problems.

If a parameter is unset (or, equivalently, set to its default value),
then the routing library will pick its preferred value for that parameter
automatically: this should be the case for most parameters.
To see those "default" parameters, call GetDefaultRoutingSearchParameters().
