Due to this theory, it became possible to develop linearly convergent methods for Linear Matrix Inequalities and other important classes of structured convex optimization problems (see [2, 12]). However, the machinery underlying the general IPM is not simple. The most efficient methods require ...

I start with an expository model to make the puzzle of why cities should contribute to a global public good explicit. It also starts introducing notation. Further, the model leads to a first observation of the role of city size. In the subsequent sections, the model will be extended by con...

Any solution that satisfies constraints (36) is a stable set which ensures the non-overlapping between two pieces. Constraints (36) together with constraints (34) ensure a feasible solution to the strip packing problem. In addition, the authors proposed a set of valid inequalities and a method...
So the chain of inequalities can also be written as Now for each real number , the “floor-plus-one” of is the unique integer such that ; hence we can conclude that It is then straightforward to give a formula for , using the fact that the th bounce starts at time , and the ball...
[12] use the notation ρ(G) to denote the cardinality of a maximum 2-packing set. The bold vertices of the cacti of Figs. 1a and 1b are examples of maximal 2-packing sets. Note that the bold vertices of Fig. 1b also form a maximum 2-packing set. Also, note that for this ...
Solve the individual inequalities as follows: |x+1| < 4 -4 < x + 1 < 4 -5 < x < 3, or x is in (-5, 3) |x+1| >= 6 x + 1 < -6 OR x + 1 > 6 x < -7 OR x > 5, or x is in (-inf, -7] U [5, inf) Since the two original inequali...
Although this is a very important theoretical idea, it was not until the 1990s that it could be implemented when Ricatti equations, linear matrix inequalities (LMIs), and Matlab toolboxes appeared and facilitated the construction of Lyapunov–Krasovskii functionals (LKF) and Lyapunov functions. Since...
Decision rules are powerful tools to manage information and to provide descriptions of data sets; as a consequence, they can acquire a useful role in decision-making processes where fuzzy rough set theory is applied. This paper focuses on the study of di
