comment Is finding the maximum of a polynomial of degree one a linear programming problem?
@MichaelC.Grant I see that my proposed equivalent is wrong. Can you indicate how to get, or if possible write as an answer, the equivalent problem using binary constraints? I tried to find my way with google, but I don't see how to do it.

@MichaelC.Grant I think, the 'max' in the problem can be 'linearized' so that the problem becomes an LP (see edit). Is it true?

comment What is the error when approximating $L^2([0,1])$ by a finite dimensional space?
@PrahladVaidyanathan Yes, thank you. I forgot to say that $X$ contains only bounded function. I added it.

@PrahladVaidyanathan I see, I miswrite the max notation. I have corrected it, is it better now?

comment What is the error when approximating $L^2([0,1])$ by a finite dimensional space?
@PrahladVaidyanathan For my understanding, the error is in the orthogonal space. If I use your formula, the error will be too big: for any $f$, the closest $g \in X_n$ to $f$ is $\sum (f,v_i) v_i$, I think.
