Skillet (band) was only together for a month when they received interest from major Christian record label ForeFront Records. In 1996 they released a self-titled debut "Skillet". It was well-received, and the trio continued to write new material as they toured the United States. The question behind the name of the band, 'Skillet', comes up often among fans and the band itself. John Cooper, the lead vocalist and founder, explains that the name was a joke at first. The two founding members had already been in different bands, with each band having a different sound and style to its music. Cooper tells
Envy-free item assignment the agents' utilities are not additive, the MNW solution is not necessarily EF1; but if the agents' utilities are at least submodular, the MNW solution satisfies a weaker property called "Marginal-Envy-Freeness except-1-item" (MEF1). There is an alternative criterion called Envy-freeness-except-cheapest (EFx): For each two agents A and B, if we remove from the bundle of B "any" item, then A does not envy B. EFx is strictly stronger than EF1. As of this writing, it is not known whether EFx allocations always exist. Given an allocation "X", define the envy ratio of "i" in "j" as: so the ratio is
