IIRC, there is no best numerical derivative algorithm. Each of them is unstable for some inputs. Oddly, integration algorithms are usually stable, though often not fast.<P>Symbolic differention is a ...

There are several optimization techniques available in PROC NLMIXED. You can choose a particular optimizer with the TECH=name option in the PROC NLMIXED statement. No algorithm for optimizing general ...

After reading “A stepwise method for tuning PI controllers using ITAE criteria” I was inspired to take a look at the current uses of PID (Proportional/Integratal ...

In recent years, research and development on quantum computers has made considerable progress. Quantum chemical calculations for electronic structures of atoms and molecules are attracting great ...
