- ALTER_ALGORITHM should be substituted when there is no mention of algorithm in alter statement. - Introduced algorithm(thd) in Alter_info. It returns the user requested algorithm. If user doesn't specify algorithm explicitly then it returns alter_algorithm variable. - changed algorithm() to get_algorithm(thd) to return algorithm name for displaying the error. - set_requested_algorithm(algo_value) to avoid direct assignment on requested_algorithm variable. - Avoid direct access of requested_algorithm to encapsulate requested_algorithm variable
