Add to ORKGAn overview is given of the role of the sparseness constraint in signal processing problems. It is shown that this is a fundamen-tal problem deserving of attention. This is illustrated by describ-ing several applications where sparseness of solution is desired. Lastly, a review is given of the algorithms that are currently avail-able for computing sparse solutions. 1
