set up to see who can catch the most. The Environment Education Foundation hosted its third ‘lionfish derby’ last month off Florida, outside the reserve, with more than $3,000 in prize money for the team catching the most fish — 109 were killed. In the waters around the Bahamas, which don’t have the same protection as Florida Keys, more than 2,000 lionfish have been killed over the past two yea...

Thomas von Brasch , Johan Byström and Lars Petter Lystad Optimal Control and the Fibonacci Sequence

We bridge mathematical number theory with that of optimal control and show that a generalised Fibonacci sequence enters the control function of finite horizon dynamic optimisation problems with one state and one control variable. In particular, we show that the recursive expression describing the first-order approximation of the control function can be written in terms of a generalised Fibonacc...

Value Framing: A Prelude to Software Problem Framing

Software problem framing is a way to find specifications for software. Software problem frames can be used to structure the environment of a software system (the machine) and specify desired software properties in such a way that we can show that software with these properties will help achieve the required effects in the environment. Actually framing a software problem, i.e. finding suitable p...
