### Output Parameters of Algorithms  
Each presented particular algorithm contains its own group of output parameters that are displayed after processing of input parameters. Simulation results can be presented in the Matlab command window, stored in xlsx format file, or displayed in graphs. After a presentation of simulation results, original input parameters can be arranged and adapted simulation results can be obtained after re-starting of the selected algorithm.  
Definitions of individual output parameters:* A total number of utilized optical fibers \(N_{UHiCH\text{--}}\)corresponds to a number of all optical fibers used by the specific allocation method to serve all bandwidth requests of ONUs.
