A Constant Factor Approximation Algorithm for Event-Based Sampling
Event-Based Sampling Approximation Algorithm
2015/6/19
We consider a control system in which sensor data is transmitted from the plant to a receiver over a communication channel, and the receiver uses the data to estimate the state of the plant. Using a f...
A 5 C -approximation algorithm for minimum weighted dominating set in unit disk graph
Approximation algorithm Dominating set Weighted unit disk graph
