Logic Scenarios for Hybrid Interior Point and Active Set

Scenario: Target Excluded by Constraint, Initial Guess Not Excluded by Constraint
The most common case, where a desired optimal is impacted by the constraint. If this happens, the search progresses from the initial guess towards the (ideal) optimum, but is restricted at a barrier.
Scenario: Target Excluded by Constraint, Initial Guess Excluded by Constraint
The scenario where the constraint is triggered upon initialization; the first guess violates the constraint and the search uses a slack variable to find the pseudo-equality case at the barrier.
Scenario: Target Not Excluded by Constraint, Initial Guess Not Excluded by Constraint
The trivial case, where the initial guess does not violate the constraint, and the target optimum solution is not impacted by the constraint. The search never engages or dis-engages a constraint
Scenario: Target Not Excluded by Constraint, Initial Guess Excluded by Constraint
The 'bad initial guess' trivial case, where the initial guess violates the constraint, but the target optimum solution is not impacted by the constraint. The search exits the domain of the constraint, and will be de-activated.
