They’re not poker-related, but the ICM algorithm models these things as iteratively constructed trees. The internal coordinates of these systems can be represented as Z-matrices. These systems are encoded via ASCII (“ASS-kee”) strings in SMILES notation. (10[2]-5[1])Three (10[1])lines meet at a point (10[1])in front of a circle in a representation of these things called (10[1])the Newman projection. (10[4]-5[3])A (10[1])field (10[2])of (10[1])“mechanics” (10[3]-5[1])named for these systems calculates interactions between them via the Lennard-Jones potential. (10[3])A line-angle formula (10[1])represents the “skeleton” (10[1])of these things, (10[1])which are commonly (-5[1])represented using ball-and-stick (10[1])models (10[3])in classroom (10[2])demonstrations. (10[4]-5[1])For 10 points, (10[1])materials and computational sciences often study the modeling of what systems composed of atoms? (10[3])■END■ (10[8])
