python Programming Glossary: conjugateAn algorithm for randomly generating integer partitions of a particular length, in Python? http://stackoverflow.com/questions/10287021/an-algorithm-for-randomly-generating-integer-partitions-of-a-particular-length a partition of N not matching the length S that the conjugate partition is often of length S. That is S 10 N 100 part list.. N .random_element if len part S SAD list Partition part .conjugate if len SAD S continue This increases the rate at which partitions.. partitions that do not match S Additionally using conjugate partitions works well in many cases to produce unbiased samples..
