WebJul 13, 2012 · Otherwise, stick to boost::dynamic_bitset and increase the block size by changing its type from 'ungisned long' (4 bytes, default) to 'unsigned long long' (8 bytes). That should reduce memory allocations and improve speed for IO. ---> boost::dynamic_bitset bv. OR. Create a new custom vector type … WebI think int is easier to use for bitmask dp because it is easier to store and loop through all possible states. The main use for bitset I have seen is when you have an O(n 2) dp solution and are looking for an extra speed boost to squeeze it in the time limit. Definitely a cool trick that makes problem setters sad/apologetic when it works.
