AN ELECTROMAGNETISM-LIKE ALGORITHM FOR FIXED CHARGE SOLID TRANSPORTATION PROBLEM
Fixed charge solid transportation problem (FCSTP) is one of the main and most important problems in transportation and network research areas. To tackle such an NP-hard problem, An Electromagnetism-like algorithm (EM) is employed. To the best of our knowledge, EM has been considered for any kind of transportation problems. Due to the significant role of parameters on the algorithm’s performance...
متن کاملElectromagnetism-like Algorithms for The Fuzzy Fixed Charge Transportation Problem
In this paper, we consider the fuzzy fixed-charge transportation problem (FFCTP). Both of fixed and transportation cost are fuzzy numbers. Contrary to previous works, Electromagnetism-like Algorithms (EM) is firstly proposed in this research area to solve the problem. Three types of EM; original EM, revised EM, and hybrid EM are firstly employed for the given problem. The latter is being firstl...
متن کاملThe Coupling of Gravity to Spin and Electromagnetism
The coupled Einstein-Dirac-Maxwell equations are considered for a static, spherically symmetric system of two fermions in a singlet spinor state. Stable soliton-like solutions are shown to exist, and we discuss the regularizing effect of gravity from a Feynman diagram point of view. There are some interesting effects that result when one couples gravity, as expressed through Einstein’s equation...
متن کاملCoupling of quintessence to pseudoscalar of electromagnetism and CMB polarization
We present the full set of power spectra of cosmic microwave background (CMB) temperature and polarization anisotropies due to the coupling between quintessence and pseudoscalar of electromagnetism. This coupling induces the rotation of the polarization plane of CMB photons, thus resulting in non-vanishing B mode and parity-violating TB and EB modes. Using the 2003 flight of BOOMERANG (B03) dat...
