We’re thrilled to share that LFortran can now successfully compile and execute libprima/PRIMA. PRIMA marks the eighth production-grade, third-party code that LFortran has compiled with bit-for-bit alignment to GFortran’s output. This milestone brings us closer to our goal of compiling 10 such codes—an essential step toward achieving a beta-quality compiler.

About PRIMA
PRIMA is a package developed by Zaikun Zhang for
solving general nonlinear optimization problems without using derivatives. It
provides the reference implementation for
Powell’s derivative-free optimization
methods, i.e., COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. PRIMA means
Reference Implementation for Powell’s methods with Modernization and
Amelioration, P for Powell. The package is written in Fortran and is widely
used in the scientific community for solving optimization problems.
