... In the sequential SIMPDEL model, map data are stored as a series of grids, represented as two or three-dimensional arrays, depending on the grid cell resolution, as explained in Section 2.2. To facilitate dynamic grid repartitioning, to be explained in Section 3.1.2, a more efficient data structure is required. The map data structure used in the parallel model is shown in Figure 6. ...

... In computer science, a stack is a last in, first out (LIFO) abstract data type and data structure. A stack can have any abstract data type as an element, but is characterized by only two fundamental operations: push and pop. The push operation adds to the top of the list, hiding any items already on the stack, or initializing the stack if it is empty. The pop operation removes an item from the top of the list, and returns this value to the caller. A pop either reveals previously concealed items, or results in an empty list. ...

... In computer science, a heap is a specialized tree-based data structure that satisfies the heap property: if B is a child node of A, then key(A) ≥ key(B). This implies that an element with the greatest key is always in the root node, and so such a heap is sometimes called a max-heap. (Alternatively, if the comparison is reversed, the smallest element is always in the root node, which results in a min-heap.) The several variants of heaps are the prototypical most efficient implementations of the ... [full article] (**60** views)

... In computer science, a binary tree is a tree data structure in which each node has at most two child nodes, usually distinguished as \"left\" and \"right\". Nodes with children are parent nodes, and child nodes may contain references to their parents. Outside the tree, there is often a reference to the \"root\" node (the ancestor of all nodes), if it exists. Any node in the data structure can be reached by starting at root node and repeatedly following references to either the left or right child. ... [full article] (**61** views)

... In computer science, a hash table or hash map is a data structure that uses a hash function to map identifying values, known as keys, (e.g., a person\'s name) to their associated values (e.g., their telephone number). The hash function is used to transform the key into the index (the hash) of an array element (the slot or bucket) where the corresponding value is to be sought. ... [full article] (**78** views)

... In computer science, a trie, or prefix tree, is an ordered tree data structure that is used to store an associative array where the keys are usually strings. Unlike a binary search tree, no node in the tree stores the key associated with that node; instead, its position in the tree shows what key it is associated with. All the descendants of a node have a common prefix of the string associated with that node, and the root is associated with the empty string. Values are normally not associated ...
