It offers a limited solution to the problem of molecular cycle perception. Unlike the set of all cycles, an SSSR can filter useless or interfering envelope cycles. Unlike the set of all cycles, an SSSR offers no … Visa mer As the name suggests, an SSSR is a subset of cycles within a molecular graph. Before going further, it's important to understand why a cycle subset should be used in the first place. Can't any problem be solved with the set … Visa mer Before discussing ways to filter cycles, it's crucial to put the entire concept of cycle sets on a more solid mathematical footing. The key to doing so is cycle space. The definition … Visa mer Cycle space and cycle addition suggest a special role for certain cycles. In particular, some members of cycle space can be viewed as precursors … Visa mer Cycle space's mathematical grounding enables provable statements and valid generalizations to be made. This grounding desirable because it's wasteful to work on implementing an algorithm only to discover a … Visa mer

Many have the goal of finding a "smallest set of smallest rings", so are called an SSSR algorithm. Frequently the easiest way to get the ring count from a toolkit comes as a direct consequence of computing the SSSR. Note though that ring identification is not necessary for this task.
