MPC: multiprecision C library for arithmetic of complex numbers

Mpc is a C library for the arithmetic of complex numbers with arbitrarily high precision and correct rounding of the result. It is built upon and follows the same principles as Mpfr. The library is written by Andreas Enge, Philippe Théveny, Paul Zimmermann and Mickaël Gastineau and is distributed under the Gnu Lesser General Public License.

Open-loop or Closed-loop (reactive) Path planning?

When we do path planning for collision avoidance, we can realize it open-loop or closed-loop. The open-loop method is to use an inherent simplified model, say, Bicycle model, for example, and propagate the system forward with an optimal input by…
