#2957: reviewed implementation and made some adjustments.

The "maximum lift of whole aircraft" is only described in the arXiv version of the paper but has been removed in the peer-reviewed version for ESWA. There seems to be an error in the pre-print (x5 and x6 stand for only one variable in the original formula and the ranges for valid values are missing).

I decided to keep the problem and assumed a rather large range to make the problem more interesting for benchmarking purposes. All differences to the published version of the problem instances are described.

#2964: edited MathMenu.js in MathJax.zip and commented out code which caused problems:

if (MENU.msieFixedPositionBug) {
MSIE can't do fixed position, so use a full-sized background
and an onresize handler to update it (stupid, but necessary)
div.width = div.height = 0; this.Resize();
attachEvent("onresize",this.Resize);
} else {

otherwise, use a fixed position DIV to cover the viewport
bg.style.position = "fixed";

}

...

/* if (this.msieFixedPositionBug) {detachEvent("onresize",MENU.Resize)} */
