Alchemical paths and derivatives hold great promise for the development of gradient based optimization algorithms in chemical compound space. I will discuss the foundation and the limits of various approaches based on density functional theory for the construction and evaluation of such quantities [1,2]. Thereafter, I will present results from applications that deal with controlling electronic structure properties, or ab initio binding energies.
