Differentially private spatial decomposition of 2D data for range queries

Implementing indexing and searching techniques for spatial data by creating an R-tree using Python.

Bounded Range Query

Optimizing Range Queries with 2D Location Data using Google S2

Online Maximum Independent Set of Hyperrectangles

Here we have implemented B-Plus Tree for data block indexing as a data system project

This repository contains simple implementations of Segment Trees and Interval Trees, which were developed as part of a university project at the Computer Engineering and Informatics Department of the University of Patras. They include functions for range and stabbing queries.

cses problem set solution for competitive programming.

A hybrid search system combining B+ Trees for range filtering and HNSW for approximate nearest neighbor (ANN) search. Features bulkloading for efficient tree construction, HNSWLib integration, and dynamic switching between brute-force and ANN search for optimal performance. Supports binary data processing and visualization with Graphviz.

Python implementation of Mo's Algorithm - a method for answering a series of range queries on the same array. The repository provides a general interface for Mos operations
