Ranges (hard constraints) refer to the limits that you set on the values of the adjustable cells (chromosomes).  You can set maximum and minimum values for some or all of the adjustable cells at once or you can set separate maximum and minimum values for each adjustable cell.

To select adjustable cells:

1.  Type the cell references in the Adjustable cells (chromosomes) edit box or select the cell from the worksheet using the mouse.

2.  Click on the AutoDetect button to enable GeneHunter to search for the adjustable cells.

Chromosome Ranges May Be Cell References

Ranges for adjustable cells (maximum and minimum values of chromosomes) can be set as references to cells on the worksheet containing the minimum and maximum values.

To specify ranges for adjustable cells:

1.  In the show list options on the GeneHunter Dialog Screen, click on ranges.

2.  Click on the Add button to display the dialog box below.

3.  Either type in the cell reference or select it on the worksheet using the mouse.

4.  Click on the arrow and select whether you want the adjustable cell to be greater than, less than, or equal to a value in the condition box.

5.  If you want the adjustable cell to be equal to a value in the condition box, either type that value in the condition edit box or select a cell from the worksheet using the mouse.

This feature allows you to change the range values in the worksheet rather than in the GeneHunter dialog box.

Note: If the range values in the worksheet change during evolution, GeneHunter will use the range values that were present at the beginning of evolution.
