, The choice of the final solutions between the different proposed ones can be based on some constraints that should be respected. For example, and under the LCE policy, if T c = 20% and ? = 1.2 (Table 3.1) and if the priority is to minimize the content provider load (f 1 (X)), then the allocation X = (1088, 800, 2208) is the best one. In case when the 2Q scheme is used, if ? = 1.0 and T c = 15% (Table 3.2) and one wants to minimize first the average distance ratio (f 2 (X)), then the allocation X = (1408, 768, 896) is the one to choose, functions approach and testing two different caching schemes: LCE (Table 3.1) and 2Q (Table 3.2). Depending on the Zipf law's parameter ?, the total cache resources available T c and the adopted caching strategy, different solutions will be generated by GRASP, vol.3, p.12
