Core Architecture

QuantumProgram is the abstract base shared by every quantum algorithm in Divi. VariationalQuantumAlgorithm extends it with the variational-parameter machinery used by VQE, QAOA, PCE, and CustomVQA. SolutionEntry is the uniform return type for decoded solutions.

ParamHistoryMode

Accepted values for param_history(): "all_evaluated" returns every parameter vector seen during optimization; "best_per_iteration" returns only the best vector from each iteration. alias of Literal[‘all_evaluated’, ‘best_per_iteration’]
