using new for each node and value, combined with virtual dispatch tends to be a c++ anti-pattern. It looks like you are writing other languages in C++ syntax, motivated by promises of speed.
The actual benefits of C++ come when you approach problems differently. This is a case where more exposure to C helps you avoid all the Java isms.
Things to consider:
- can you allocate memory for the whole system?
- can you make types homogenous so they can fit in tight arrays (unions are common for nodes)
- can you batch similar types
- specially for auto diff/math can you represent operations as a stack instead of a tree?
I am only bringing this up because you said your goal was to learn C++.
