1. A system for generating a unified determination based on subdeterminations, the system including: a first score processor generating a first subdetermination based on first criteria, wherein the first criteria is a front end risk score; a second score processor generating a second subdetermination based on second criteria, wherein the second criteria is a back end risk score; a combination score processor generating a unified determination based on the first subdetermination and the second subdetermination, the combination score processor including: an iteration control portion assigning, using iterative processing, an assigned weighting respectively to the first determination and second determination; a feasibility determination portion determining if the assigned weighting satisfies at least one constraint; a comparison portion comparing the assigned weighting to an optimized weighting, which was previously determined, to determine if the assigned weighting is improved over the optimized weighting; and if the assigned weighting is improved, then the comparison portion assigning the assigned weighting to be the optimized weighting; wherein the first subdetermination is a first score, and the second subdetermination is a second score; wherein the feasibility determination portion determining if the assigned weighting satisfies at least one constraint is performed using a first relationship including parameters, the parameters including the first subdetermination, the second subdetermination, the assigned weighting and a first objective parameter, and comparing a result of the first relationship with a first constraint value; wherein the determining if the assigned weighting satisfies at least one constraint is performed using a second relationship including parameters, the parameters including the first subdetermination, the second subdetermination, the assigned weighting and a second objective parameter, and comparing a result of the second relationship with a second constraint value; and wherein the comparison portion comparing the assigned weighting to an optimized weighting to determine if the assigned weighting is improved over the optimized weighting includes: using a first relationship including first parameters to generate a first result, the first parameters including the first subdetermination, the second subdetermination, the assigned weighting and a first objective parameter; and using a second relationship including second parameters to generate a second result, the second parameters including the first subdetermination, the second subdetermination, the optimized weighting and the first objective parameter, and comparing the first result to the second result; and the system constituted by a tangibly embodied computer processing machine.
