What have you tried? If nothing, then why not? Just evaluate the objective at every point in a regular grid within the search space. Then use plot, or perhaps plot3, or surf as you wish, etc. WTP?
If you have more than 2 parameters, then you will need to buy a higher dimensional monitor to view the plot on. They can be expensive, and will be only available in the distant future. I understand that Skynet can supply them, but watch out for the Skynet sales reps, as they are often a bit unfriendly. Say high to Ahnuld for me.
