Authority in expert opinion?

Question

Programming

There are three experts and they have authority:
Expert #1 - 1weight
Expert #2 - 1weight
Expert #3 - 0.5weight
if Expert #1 and Expert #2 give the same answer, then their opinion will be accepted as true. Opinion #3 will be ignored.
if Expert #1 and Expert #2 say a different answer, and #3 says the same answer as #1, then opinion #1 #3 will be true
if Expert #3 and Expert #2 say a different answer, and #1 says nothing, there will be uncertainty.
how to code it? yes, you can do a bunch of ifs, but I might have a lot of experts.
maybe you can google it somehow and there will be a super cool algorithm with a formula?

Answer 1

The sum of the expert weights for each of the available answer options.
The answer with the maximum amount is the solution. If the answers with the maximum sum of weights are greater than 1, then the situation is uncertain.
