Describe local and global optimization ?

Local optimizations

These only consider information local to a function definition. This reduces the amount of analysis that needs to be performed (saving time and reducing storage requirements) but means that worst case assumptions have to be made when function calls occur or global variables are accessed (because little information about them is available).

Global optimization

The most common form is the minimization of one real-valued function f in the parameter-space x e P. There may be several constraints on the solution vectors xmin. In real-life problems, functions of many variables have a large number of local minima and maxima. Finding an arbitrary local optimum is relatively straightforward by using local optimisation methods. Finding the global maximum or minimum of a function is much more challenging and has been practically impossible for many problems so far. The maximization of a real-valued function g(x) can be regarded as the minimization of the transformed function f(x):=(-1).g(x).

difference between medicines and supplements


Medicines are products which contain active agents and which are used by humans (or animals) in order to Prevent, Ease, Diagnose, Treat; illnesses, symptoms of illnesses, pain or to affect a bodily function.
 
Herbal medicines are a special group of medicines which typically contain dried plants, extracts of herbs or other naturally occurring agents. The active agents may not occur in concentrations which are considerably higher than in nature. Herbal medicines can only be approved for the treatment of less serious illnesses.
 
Strong vitamin and mineral products are a group of medicines, where the active agents are exclusively vitamins and/or minerals, and where the content of vitamins and minerals is considerably higher than the normal daily requirement for adults. Strong vitamin and mineral products can only be approved to prevent and heal the so-called deficiency conditions.
 
Nutritional supplements are products which supplement the normal diet with nutrients. For example vitamins and or oils with a high content of essential fatty acids in doses within the maximum allowable daily dose.
