2.2 Paper reviews

2.2.1: ML topics Graph Proposal Phil Ratzloff et al

Latest paper:

Here’s a link to the paper (different than the previous paper reviewed).
There are some additional updates I’m planning on making before the meeting.

P1709R4 will be the aiming for Dec 2022 publication.

CPPCON review had some naming change suggestions
OK to put requirements on random access range, and integral vertex algo and not adjacency list

Joe: O(V log(V)), could dominate V

Add examples in complex cases, With Bellman Ford ,just say same as previous example but with negative weights

Vertex_view name is a bike shed, leave it to LEWG, vertex_view_modifier?
Take cancel out

 https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2022/p1708r6.pdf March 15. 2022
D1708R7: passed Sg6, waiting for LEWG.

More Simple Statistics
2 names differ by one letter -> bike shedding should be left to LEWG
how do we return the result if we have even length range: decided return of subrange iterator that points to the medians

Is this ready to exit SG19 to SG6
Approved to go to SG6.
