From Invariant Checking to Invariant Inference Using Randomized Search
Invariant Checking Invariant Inference Randomized Search
2016/5/24
We describe a general framework c2i for generating an invariant inference procedure from an invariant checking procedure. Given a checker and a language of possible invariants, c2i generates an infere...
Trinary-Projection Trees for Approximate Nearest Neighbor Search
Approximate nearest neighbor search KD trees trinary-projection trees
2016/1/23
We address the problem of approximate nearest neighbor (ANN) search for visual descriptor indexing. Most spatial partition trees, such as KD trees, VP trees and so on, follow the hierarchical binary s...

2009/9/4
A new genetic algorithm (GA) methodology, Bipopulation-Based Genetic Algorithm with Enhanced Interval Search (BGAwEIS), is introduced and used to optimize the design of truss structures with various c...
Array Pattern Nulling by Phase and Position Perturbations with the Use of a Modified Tabu Search Algorithm
Array Pattern Nulling Phase and Position Perturbations Modified Tabu Search Algorithm
2009/7/28
A useful and flexible method based on the tabu search algorithm for the pattern synthesis of linear antenna arrays with the prescribed nulls is presented. Nulling of the pattern is achieved by control...
Paths Beyond Local Search: A Tight Bound for Randomized Fixed-Point Computation
Local Search:Tight Bound Randomized Fixed-Point Computation
2012/12/3
In 1983, Aldous proved that randomization can speedup local search. For example, it reduces the query complexity of local search over grid [1 : n]d from Θ(nd−1) to O(d1/2nd/2). It remains open w...
