Vazirani, Vijay V; Khuller, Samir (1991)We show that obtaining the lexicographically first four coloring of a planar graph is NP-hard. This shows that planar graph four-coloring is not self-reducible, assuming P≠ NP. One consequence of our result is that the ...
Biswas, K; Mahalanabis, A (1972)The aim of this note is to report an algorithm for the fixed lag smoothing problem of a time delayed system whose observations contain colored noise. This is derived by looking at the appropriate components of a filtering ...
Least-squares state estimation in time-delay systems with colored observation noise: An innovations approach Mishra, J; Rajamani, V (1975)the method of innovations approach has been applied to develop an algorithm for the least-squares state estimation of a non-stationary linear discrete system with multiple time-delays, based on observations involving ...
