libboost-graph-dev 1.71.0.0ubuntu1 (s390x binary) in ubuntu focal

 This package forms part of the Boost C++ Libraries collection.
 .
 Graphs are mathematical abstractions that are useful for solving
 many types of problems in computer science. Consequently, these
 abstractions must also be represented in computer programs. A
 standardized generic interface for traversing graphs is of utmost
 importance to encourage reuse of graph algorithms and data structures.
 .
 This package is a dependency package, which depends on Debian's default
 Boost version (currently 1.71).
