# Abstract
Variational quantum eigensolver (VQE) is a hybrid quantum algorithm to find the ground state of an input Hamiltonian. There are several classical optimizer available in Qiskit Aqua such as…

According to the Forest docs, the "new way" of minimizing an anzatz does the following:
1. declares parameters in the program, and
2. uses the memory_map dict as an argument to qc.run().
But you…
