Kick3 is an extension of the Kick-fragment algorithm, defined as being paired with a computationally efficient method such as third-order self-consistent-charge densityfunctional tight-binding (DFTB3). In the study by Matthew A. Addicoat et al. on page 2591, arbitrary molecular fragments from a pre-described ordered list of an arbitrary number of different fragments are placed in a 3-dimensional space, in much the same manner as haphazard Legos. The structure generation algorithm is conformationally aware and will create conformational isomers by random rotations around pre-described rotatable bonds, which is useful, for example, for the side chains of ionic liquid ions.
