1.2 Adopt agenda1.3 Approve minutes from previous meeting, and approve publishing previously approved minutes to ISOCPP.org1.4 Action items from previous meetings2. Main issues (125 min)2.1 General logisticsMeeting plan, focus on one paper per meeting but does not preclude other paper updates: Jan 13, 2022 02:00 PM ET/1900 UTC: Review Feb 10, 2022 02:00 PM ET/1900 UTC: Stats Mar 10, 2022 02:00 PM ET/1900 UTC: Graph
Phil presenting:
longer tuples, C++23 zip is needed
Ranges out, views in
with an edge, many algo just need a target key and no source key.
Concepts: Other functions
Data structures: direct_adjacency vector-> csr_graph
Additional Work: graph range, algorithms, physical edge list, concepts for views
this is more modern
write algo based on infrastructure the package provides using djkstra's shortest path; another category is to write temporary on each edge
Richard shows some new additions to stats
basic freestanding all the same drop the constraints of the concept
concern about your type may work in MS STL , but not GCC, or clang, it would be up to implementation STL; it is how complex number works: specified to work for float and double, long double and happens to work inline: then wording will follow std complex
4.2 accumulator
used to derive from a common parent leading to RTTI
but now no more virtual function, more parallelizable
copy/move/assignment constructors can be removed as language provides those but add statement to say it is copyable,etc
advise not use auto return type for trivial return type like result, please document rationale as well,
moving away from abbreviations acc=accumulate/accumulator
maybe stats namespace under std
change typename to class
follow algorithm section of standard
Nan needs to be used for infinity
