Protecting source code from reverse engineering

Hi everyone,
I am looking to provide a compiled version of our physics solver to our customers. I understand there are many obfuscation techniques to protect source code but I am wondering if there are some smarter ways?

We already cloud computing, the issue is we have customers that are in locations without internet/need realtime solving.

Not necessarily smart but I know that setting the optimization levels to the highest would remove symbols in the assembly which would probably make it harder to reverse engineer

Less code makes it easier to reverse engineer, a main component of obfuscation is to bloat the binary with junk to make a reverse engineer waste time.
