31. An important problem involved with this solution is the possibility of local minima . 32. Likewise, minima remain minima when non-negative and otherwise become maxima. 33. Likewise, minima remain minima when non-negative and otherwise become maxima. 34. Scale space continuation can be used in order to avoid these local minima . 35. Secondly, Monte Carlo variation allows the search to escape from local minima . 36. This function has a series of maxima and minima . 37. On the graph, this makes the minima more acute than the maxima. 38. In each period of 75 days it has two maxima and two minima . 39. The lines are drawn through minima in genetic space. 40. Like strictly convex functions, strongly convex functions have unique minima on compact sets.
