OK, you read some of the Fermatsearch pages, you understood some of the backgrounds of the search and learnt its history.
Now what? You found yourself willing to help the search, but there are still some questions you need answered, i.e. where should I start my search?
The first thing to do is to decide what kind of work you want to do. If you want to do some ecm curves, go to ecm link, and follow the instrucions.
If you prefer working with old-fashioned, simpler trial-factoring, download fermat.exe or GMP-Fermat in a folder of your choice, and launch it.
There are four values you need to input: From N, To N, For k and To k.
Now it's time to decide our values.
The table below shows an example of research for N=30.
|From N||To N||From k||To k||Researcher||Status|
|30||30||500,000,000,000,000||550,000,000,000,000||Fabrice Le Foulher||factoring|
|30||30||550,000,000,000,000||600,000,000,000,000||Rick van der Hoorn||factoring|
|30||30||600,000,000,000,000||650,000,000,000,000||Rick van der Hoorn||factoring|
|30||30||650,000,000,000,000||700,000,000,000,000||Fabrice Le Foulher||factoring|
|30||30||700,000,000,000,000||1,000,000,000,000,000||Fabrice Le Foulher||factoring|
Now let us try some searches on the database tables.
Just input starting and ending values of N in the boxes below, press the button and check the possible searches.
You may use the testing link to time your calculations.
Note that ranges are not always taken homogeneously, so it is advisable to test wider n-ranges , check the work done and then redefine a smaller range.
Still feeling puzzled? Don't worry, just follow the link towards available ranges.
