Skillet (band) and My Darkest Days will be supporting acts. They toured again with TobyMac in November and December as the 2010 version of the Winter Wonder Slam tour. On July 4, Skillet played at Creation Festival East, and John Cooper called it the best show of Skillet's career. In January 2011, Skillet confirmed that they would be touring with Stone Sour and Theory of a Deadman on the Avalanche Tour. The tour began at the end of March 2011 and concluded on May 8 in Jacksonville, FL. Other supporting acts include Halestorm and Art of Dying. The band had a small
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
