## Generic Graph Libraries in C++20 ## ANDREW LUMSDAINE, PHIL RATZLOFF 20 21 October 24-29 ## About Us  ## • Andrew software libraries, and large-scale graph analytics. Open-source software projects resulting from his work include the Matrix Template Library, the Boost Graph Library, and Open MPI.  results can be applied to many different practical (concrete) problems – theory

## +24 ## Improving Our Safety With a Quantities and Units Library ## MATEUSZ PUSZ ## The future is here  ## The future fundamental types – updating the core language rules – providing safer high-level abstractions in the library ## C++ developers needs help • Many C++ engineers are expected to write life-critical software today quantities and units library ## • Compile-time safety – correct handling of physical quantities, units, and numerical values ## mp-units: C++20/23 quantities and units library ## • Compile-time safety

## A Physical Units Library For the Next C++ Mateusz Pusz September 15, 2020 ## Motivation, Existing Practice, Challenges  slide number. ## QUICK START ## Physical Units library in a nutshell // simple numeric operations static_assert(10_q_km / 2 == 5_q_km); ## Physical Units library in a nutshell ## // simple numeric operations static_assert(1_q_h == 3600_q_s); static_assert(1_q_km + 1_q_m == 1001_q_m); ## Physical Units library in a nutshell // simple numeric operations static_assert(10_q_km / 2 == 5_q_km); // unit conversions

stdx::interval, a library for intervals on totally ordered sets Eric Hughes, Meadhbh Hamrick ## I n brief stdx::interval implements the mathematical sense of an interval on a totally ordered set. The library reasons reasons about intervals as sets, not as interval expressions. The library is header-only and targets C++20. It is available under the MIT License. ## Features ## Predicates Membership. Determine if a point \infty,b](-\infty,b)(-\infty,+\infty) Generic. The library handles the differences between discrete (e.g. int and other integral types) and continuous (string
