Total resource time for models solved optimal/feasible by solver A and solver B.

See the solver return definitions for optimal/feasible model and solve statuses. Solutions are not checked for how close they are to oneanother. Resource times are considered the same, if they are within 10% of eachother. A solver is considered faster than another, if it is less than 50% faster than the other. A solver is considered much faster than another, if it is more than 50% faster than the other.

A solver is considered to have a better objective function value, if the relative objective value difference is greater than 1.00E-05.
