We consider the inverse Landau-Zener problem which consists in
finding the energy sweep functions 
resulting in the required time
dependences of the level populations for a two-level system
crossing the resonance one or more times during the sweep.
We find
sweep functions of particular forms that let manipulate the system
in a required way, including complete switching from the state 1
to the state 2 and preparing the system at the exact ground and
excited states at resonance.
