The Weapon-Target Assignment (WTA) problem aims to assign a set of weapons number assets (targets), such that the expected value survived targets is minimized. WTA nonlinear combinatorial optimization known be NP-hard. This paper applies several existing techniques linearize problem. One linearization technique (Camm et al. in Oper Res 50(6):946–955, 2002) approximates terms via convex piecewis...

The linear and non-linear Klein-Gordon equations are considered. fractional complex transform is used to convert the on a continuous space/time fractals ones Cantor sets, resultant solved by local reduced differential method. Three examples given show effectiveness of technology.
