  Using complex Langevin method we probe the possibility of dynamical
supersymmetry breaking in supersymmetric quantum mechanics models with complex
actions. The models we consider are invariant under the combined operation of
parity and time reversal, in addition to supersymmetry. When actions are
complex traditional Monte Carlo methods based on importance sampling fail.
Models with dynamically broken supersymmetry can exhibit sign problem due to
the vanishing of the partition function. Complex Langevin method can
successfully evade the sign problem. Our simulations suggest that complex
Langevin method can reliably predict the absence or presence of dynamical
supersymmetry breaking in these one-dimensional models with complex actions.
