The Reissner?Nordstrom spacetimes and some generalised Reissner?Nordstrom spacetimes are analysed. The blackhole solutions are considered. The generalised Reissner?Nordstrom spacetimes with a cosmological-constant term, endowed with a Schwarzschild solid...

In parameterized complexity, it is well-known that a parameterized problem is fixed-parameter tractable if and only if it has a kernel?an instance equivalent to the input instance, whose size is just a function of the parameter. The size of the kernel ca...

Deterioration of the searchability of Pareto dominance-based, many-objective evolutionary optimization algorithms is a well-known problem. Alternative solutions, such as scalarization-based and indicator-based approaches, have been proposed in the litera...

Solving mixed-integer nonlinear programs (MINLPs) is hard from both a theoretical and practical perspective. Decomposing the nonlinear and the integer part is promising from a computational point of view. In general, however, no bounds on the objective v...

This paper considers a variant of the Vehicle Routing Problem with Time Windows, with site dependencies, multiple depots and outsourcing costs. This problem is the basis for many technician routing problems. Having both site-dependency and time window co...

Thick ellipsoids were recently introduced by the authors to represent uncertainty in state variables of dynamic systems, not only in terms of guaranteed outer bounds but also in terms of an inner enclosure that belongs to the true solution set with certa...
