a*log(1+b/a)>c

a,b,c are all positive variables，can this constraint be expressed in CVX？

a*log(1+b/a)>c

a,b,c are all positive variables，can this constraint be expressed in CVX？

`-rel_entr(a,a+b) >= c`

CVX will treat `>`

as being `>=`

. So if you need strict inequality, you should change it to `-rel_entr(a,a+b) >= c + small_positive_number`

, where `small_positive_number`

is perhaps 1e-5 or 1e-6.

Thank you sir, I wanna ask you about another expression

can log(1+c1*g/(c2*g+c3)) be expressed in CVX?

where g is variable
