I noticed that my mind lives in the ambiguity (ex: more than one way to face any problem), might this be related to adhd present in asperger's?

Not black and white.: This is more likely to be due to being bright, flexible and seeing the world in many shades of gray (vice black and white). This sounds like a positive - i wouldn't try to pathologize it.

Mental inflexibility: , a deficit in executive functions found in Asperger syndrome &/or adhd is the antithesis of your description. If your ability to problem-solve or make a decision is harmfully impacted by a compulsion to consider every possible permutation of every potential solution to every problem, seek psychological & psychiatric evaluations to determine if you have ocd or another anxiety disorder.
