It depends. Since "heuristic" means "by trial and error", i.e. experimentation, a heuristic algorithm might encounter different results for each observation, and may well give a different answer in the end. This depends on the sequence of the observations, the stability or instability of each result, and whether or not fuzzy logic is part of the algorithm. My answer is "generally, no", but if the algorithm always takes the same path, and always gets the same intermidiate results, then the final result would always be the same. Again, it depends.
It can not mathematically be proven that always it will give you an improvement.
If all else fails, read the instructions.
Search engines ranking the result based on the search engine's algorithms. At present, Google panda and penguin updates are playing a more important role to give raking results in the search engine.
Give her a very nice necklace,or a ring for her always being by your side.
Any number multiplied by zero will always give the result of zero.
They both can only give the result TRUE or FALSE. However, given the same values, they will not always give the same result. All conditions in an AND function must be fulfilled to give a TRUE result whereas only one needs to be fulfilled in an OR function.
Processing of data mostly includes sorting algorithms.
When you multiply an odd number by an even number, you are essentially adding an even number of odd numbers together. Since adding an even number of odd numbers will always result in an even number, the product will be even.
Universal indicator is just that - an indicator. It is not intended as an accurate measurement system.
there is always an error factor but with a blood test you can be pretty sure its correct.
It prevents loops in a switched network with redundant paths.
Forensic reports always give you accurate result with ample research, else don't accept it as real.
