For hw4, I just started and processed the logic, type and typearray. The
intuition tells me I should process the nodekinds bottom up, but after
typearray, I realized I lost my init errors. Will there be any possibility

$ cat SortedFile.txt | perl -wnl -e '@f=<>; END{ foreach $i (reverse 0 .. $#
f) { $r=int rand ($i+1); @f[$i, $r]=@f[$r,$i] unless ($i==$r); } chomp @f;
foreach $line (@f){ print $line; }}'

foreach (ObjectA a : aList) {
a.convert(conversionParameter1, conversionParameter2);

发帖数: 119 | 19 你可以这样想，到达均匀分布的情况下之后，所有点的矢量和为零。也就是说对于每个点，其余点的矢量和应该是该点的反向矢量。注意，使用球坐标系
所以你可以试试下面的算法
points[1..k];
loop
maxdistance = 0;
foreach point in points
other = - sum (points - point);
point = (point * phi) + (other * (1 - phi);
maxdistance = max(maxdistance, other - point);
end foreach
while (maxdistance > threshold); |
