可以使用 Oracle 提供的 DBMS_CRYPTO 包来加密 Price 和 PhoneNumber 字段。首先需要创建一个加密密钥，然后使用该密钥对数据进行加密和解密。 以下是加密 Price 和 PhoneNumber 字段的示例 SQL 代码： -- 创建密钥 DECLARE key_raw RAW(32) := utl_raw.cast_to_raw('my_secret_key'); encryption_type PLS_INTEGER := dbms_crypto.ENCRYPT_AES256 + dbms_crypto.CHAIN_CBC + dbms_crypto.PAD_PKCS5; key_handle NUMBER; BEGIN key_handle := dbms_crypto.create_key( key_length => 32, key_type => dbms_crypto.TYPE_AES256, key_source => key_raw ); END; / -- 加密 Price 字段 UPDATE PRODUCT SET Price = dbms_crypto.encrypt( src => to_char(Price), typ => encryption_type, key => key_handle ); -- 加密 PhoneNumber 字段 UPDATE CUSTOMER SET PhoneNumber = dbms_crypto.encrypt( src => PhoneNumber, typ => encryption_type, key => key_handle ); 注意，在实际应用中，需要妥善保管密钥，确保数据的安全性。

Minorization-maximization (MM) algorithm是一种常用的优化算法，用于求解非凸问题或含有约束的优化问题。该算法的基本思想是通过构造一个凸下界函数来逼近原问题，然后通过求解凸下界函数的最优解来逼近原问题的最优解。具体步骤如下： 1. 初始化参数 $\theta_0$，设 $k=0$； 2. 构造一个凸下界函数 $Q(\theta|\theta_k)$，使其满足 $Q(\theta_k|\theta_k)=f(\theta_k)$； 3. 求解 $Q(\theta|\theta_k)$ 的最优值 $\theta_{k+1}=\arg\min_\theta Q(
