In function \"expand_root\" (alex.h), all pointers must be assigned to resolve issue #26 .\r\n2. The case that the slope is equal to 0 must be carefully check to prevent emergence of infinite.\r\n3. In function \"significant_cost_deviation\" and \"catastrophic_cost\" (alex_nodes.h), if the slope is equal to 0, keys of the data node are equal and should not be split. Otherwise, one key cannot be mapped to different data nodes.\r\n4.  In function \"expand_root\" (alex.h), the computation of expansion factor should be more precise for long long int, especially for \"ceil\" function, or expansion factor may be equal to 1.\r\n\r\nCo-authored-by: Zhaoyan Sun <53212907+Curtis001@users.noreply.github.com>","shortMessageHtmlLink":"attempt to fix some bugs of null pointers, 0 slopes, and 1 expansion …"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAAEE4IUVwA","startCursor":null,"endCursor":null}},"title":"Activity · microsoft/ALEX"}
