The whatever coefficient is the number that each variable (starting from w) goes to before flicking over to 0 and shifting the next variable up by one. The smaller it is, the faster that calculator will run but the less likely you are to find a solution. The larger it is, the more in-depth the calculator will run to but the slower it will be.
See inside!!! Also (Justin) 4 things: 1) the coefficients v,w,y and z are not the variables w,x,y and z, these coefficients represent the solutions for x because the code runs backwards- every equation has 4 real natural number solutions, but the program is checking to see if it fits the "form" of the quartic in the email i sent you. 2) to edit the whatever coefficient you have to click "see inside" and then change the code. i can help you with that if you want just mail me 3) the program is designed to stop itself once it detects that the equation has the necessary "form" so don't worry if it looks like the numbers are ticking off faster than you can count! 4) If it runs through the program without finding positive results, the cat will display the words "nope nothing makeit bigger" this refers to increasing the whatever coefficient to have a more in-depth search (see above)
