We’ve already received 3 submissions with solutions to our November challenge “Vacation Days Advanced” using different tools: FICO Blaze Advisor, OpenRules, and DT5GL . Contrary to the 2016 challenge “Vacation Days”, this one doesn’t have inter-rules relationships like “apply this rule only if you didn’t apply this rule”. It rather provides a constraint across all rules (“The total number of vacation days cannot exceed 29”) and asks a decision engine to maximize the total number of given vacation days. Please compare the provided solutions and share your thoughts here.
