To hash a tree, hash its root, pick a child number H mod n, where n is the number of children of root, and recursively hash the subtree of this child. This seems to be a bad option if trees differ only deeply near the leaves.

WebHash Table Program in C. Hash Table is a data structure which stores data in an associative manner. In hash table, the data is stored in an array format where each data value has its own unique index value. Access of data becomes very fast, if we know the index of the desired data. WebTo address this shortcoming, we introduce dynamic inverse reinforcement learning (DIRL), a novel IRL framework that allows for time-varying intrinsic rewards. Our method parametrizes the unknown reward function as a time-varying linear combination of spatial reward maps (which we refer to as "goal maps"). We develop an efficient inference ...
