Abstract: Method, system, and computer program product for visualization of patient treatments are provided. The method includes: selecting a patient; retrieving data records of patients with similar conditions requiring treatment to the selected patient; and building a tree structure for display with nodes of treatment options and a temporal axis showing treatment results of the similar patients. The tree structure includes representing side effects of a treatment option at a node including a visualization of the strength of the side effect. The tree structure also includes providing edges between the nodes representing a length to progression of the condition requiring treatment.

Abstract: A method for processing data includes reading respective initial substrings of the strings in a group, and computing respective codewords for the initial substrings. The codewords indicate differences between the substrings and point to the strings from which the substrings were respectively read. The codewords are arranged in a heap, which includes a tree of nodes. Each node has no more than two children and has a respective codeword pointing to a string that is in a predetermined ordinal relation, based on the lexicographical ordering, to the strings pointed to by the codewords of the children of the node. A list of one or more of the strings is output in accordance with a lexicographical ordering by selecting one or more of the nodes in the heap and reading the strings that are pointed to by the corresponding codewords.
