+1+2+3. personally, any edema is bad.... Oct 16, '04. I rate it on the pitting by how many seconds it takes to return to normal after an indent. If it takes 1-3 seconds I rate it a one, 4-6 seconds a two, more a three and after that I tell them how many seconds and say beyond a three.
A heuristic technique (/hjáµ¿ËrÉªstáµ»k/; Ancient Greek: Îµá½ÏÎ¯ÏÎºÏ, find or discover), often called simply a heuristic, is any approach to problem solving, learning, or discovery that employs a practical method not guaranteed to be optimal or perfect, but sufficient for the immediate goals.
A heuristic is a practical way to solve a problem. It is better than chance, but does not always work. A person develops a heuristic by using intelligence, experience, and common sense. Trial and error is the simplest heuristic, but one of the weakest. Rule of thumb and 'educated guesses' are other names for simple heuristics. Since a heuristic is not certain to get a result, there are always exceptions.
