The three common elements of an optimization problem are the objective function, constraints, and decision variables. The objective function defines what is being optimized, whether it's maximization or minimization. Constraints are the restrictions or limitations on the decision variables that must be satisfied. Decision variables are the values that can be controlled or adjusted to achieve the best outcome as defined by the objective function.
Well, the fact that you said "trace elements" makes me think you probably don't mean hydrogen or helium, which are present in large amounts in stars.After those, the three most common elements would be oxygen, carbon ... and then it gets complicated. Most probably the third would be neon, but iron and nitrogen are also pretty common.
Calcium, carbon, and oxygen are the three elements that make up calcite, which is a common mineral form of calcium carbonate.
The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.
Water: contains hydrogen and oxygen elements. Table salt: contains sodium and chlorine elements. Aluminum foil: contains aluminum element.
Carbohydrates are primarily composed of three elements: carbon (C), hydrogen (H), and oxygen (O). These elements are typically arranged in a ratio of about 1:2:1, which is characteristic of sugars and starches. Common examples of carbohydrates include glucose, fructose, and sucrose, all of which contain these three elements.

There are three common elements: C, H, and O.
There are three common elements: C, H, and O.
Carbon bonds with chlorine potassium and other solids and liquids to make salts.
The three most common elements of life are carbon, hydrogen, and oxygen. These elements are essential components of biological molecules like carbohydrates, lipids, nucleic acids, and proteins that make up living organisms.
