求翻译：计算每个中继站到其相应的外接圆的距离之和，并与上限对比，如果更小则认为是可行的，如果更大，则将每一个中继站移动到相应的外接圆并返回步骤2是什么意思？

Each relay station to the circumcircle of distance, and compared with the upper limit, if the smaller is considered to be feasible, if greater, each relay station will move to the circumcircle and return to Step 2

Calculation of each repeater station to their corresponding external circle, and the distance between the upper limit of the contrast and more small, considered to be, if feasible, if larger, each relay will move to the corresponding outer ring and return to step 2

Calculates each relay station to its corresponding circumcircle sum of distance, and with upper limit contrast, if smaller thought is feasible, if bigger, then moves each relay station to the corresponding circumcircle and returns step 2

Each relay station to the sum of the distances of the circumscribed circle, and with maximum contrast, if smaller, are considered to be feasible, and if more, then each relay station moving to the circumscribed circle and return to step 2
