Detailed Description

The basic interface of an oracle.

An oracle predicts the answers to our problem. It's the incarnation of the individual/team we've evolved.

Note

The output of basic_oracle and src::interpreter can be similar or distinct, depending on the task (regression, classification...). E.g. for regression problems basic_oracle and src::interpreter calculate the same number. basic_oracle always calculates a meaningful value for the end-user (the class of an example, an approximation...) while src::interpreter often outputs an intermediate value that is just a building block for basic_oracle (e.g. classification tasks with discriminant functions). The typical use chain is: src::evaluator –[uses]--> basic_oracle –[uses]--> interpreter.

Another interesting function of basic_oracle is that it extends the functionalities of interpreter to teams.
