A parabola is a curved line with particular characteristics. Any point on the curve is the same distance from a fixed point and a fixed straight line. The result looks like half of an ellipse or the ...

In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following diagram ...

This is a preview. Log in through your library . Abstract We consider a planning problem that generalizes Alcuin's river crossing problem to scenarios with arbitrary conflict graphs. This ...

We consider the number of vertex independent sets i(G). In general, the problem of determining the value of i(G) is NP-complete. We present several upper and lower bounds for i(G) in terms of order, ...
