Thoughts.
How is it common to solve these types of problems?
It's a problem to find the minimum of an x + exp(-ax)-like expression, which can be solved analytically.
Official Explanation
Oh, you do three-minute search?
It also said "okay" to solve analytically.
However, the trap is that the minimum value of x can be negative.
