Erratum: Computational Exploration of the Biological Basis of Black-Scholes Expected Utility Function

Line 5 in the first paragraph of [1] under the section Option basics appeared as follows: “A call option gives the buyer of the option the right to buy the underlying asset at a fixed price (strike price or K) at any time prior to the expiration date of the option.” It is commonplace in derivatives literature to denote the strike or exercise price as K (e.g., refer to http://www.duke.edu/∼charvey/Classes/ba350/optval/optval.htm). However, in the body of our paper wherever the strike price variable has appeared in a mathematical context it has been denoted as X rather than K . So, for sake of maintaining consistency in mathematical notation, we hereby submit to rephrase the above sentence as follows: “A call option gives the buyer of the option the right to buy the underlying asset at a fixed strike price (or exercise price; generally denoted as either Kor X) at any time prior to the expiration date of the option.”
