Hello, friends Optimization 1:
MaximalBy[{{4.9375, {x -> -(3/4)}}, {2.0792, {x -> 2/Sqrt[
3]}}}, First]
the result is: {{4.9375, {x -> -(3/4)}}}
Optimization 2:
MaximalBy[{{79/
16, {x -> -(3/4)}}, {-1 + 16/(
3 Sqrt[3]), {x -> 2/Sqrt[3]}}}, First]
the result is: {{-1 + 16/(3 Sqrt[3]), {x -> 2/Sqrt[3]}}}
Actually, they are the same optimization problems. Why? Thank you very much!
