class picos.expressions.exp_logarithm.Logarithm(x)[source]¶

Logarithm of a scalar affine expression.

For a real scalar affine expression $x$ , this is $\log(x)$ .

Warning

When you pose a lower bound on a logarithm $\log(x)$ , then PICOS enforces $x \geq 0$ through an auxiliary constraint during solution search.

__init__(x)[source]¶
