लोगो के संदर्भ में लोगो मान्यता के लिए बंडल न्यूनतम हैशिंग:

मान लीजिए कि हमारे पास बंडल {2,5,18,444,678} और {2,5,79,368,841} हैं और शब्दावली का आकार 1M है यदि हमारे पास केवल 1 स्केच प्रति बंडल है तो हमें 1 हां फंक्शन की आवश्यकता है जो 1 एम पूर्णांक को [0,1] में समान वितरण से मूल्यों के निर्धारण के लिए निर्धारित करता है। प्रत्येक कॉल के लिए हैश फ़ंक्शन को निश्चित बीज होना चाहिए। 4-स्केच के लिए हमें 4 बीजों के साथ ही हैश फ़ंक्शन की आवश्यकता होती है। क्या विचार सही है?

या हम बेतरतीब ढंग से सेट (बंडल) से न्यूनतम हश शब्द के रूप में एक संख्या चुन सकते हैं, क्योंकि वे सेट के यादृच्छिक क्रमबद्धता का प्रतिनिधित्व करते हैं?

कागज में आवश्यक हैश फ़ंक्शंस?

क्या मुरमुरहेश 3 काम कर सकता है?

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
