Hi,
Doug suggested to try another variant of resolving hash collisions in
open-addressing table - using a secondary hash for increment value of
consecutive probes. Since Java Objects provide only one hashCode()
function, "secondary" hash is computed from primary hash by
xorShift(hashCode), fo
Hi,
I explored various strategies to minimize worst-case lookup performance
for MethodType keys in LinearProbeHashtable. One idea is from the
"Hopscotch hashing" algorithm [1] which tries to optimize placement of
keys by moving them around at each insertion or deletion. While a
